The yield spread has been found to serve as a valuable economic forecasting tool. This
research employs dynamic autoregressive probit downturn models using the United States yield
spread and other regional and macroeconomic variables. This study then inspects the predictive
power of the United States yield spread on the five largest urban economies in Texas, the four
largest metropolitan areas along the Texas-Mexico border, as well as the Texas state economy.
The other regional and macroeconomic variables are included in model specifications based on
characteristics of the economies being analyzed. Results indicate that a narrowing of the United
States Yield Spread for either country tends to increase the probability of recessions in all the
economies analyzed. Decreases in the real value of the peso are found to reduce the likelihood of
a recession in border economies and Texas. However, results for west Texas intermediate oil price
are mixed and suggest that for some economies when oil prices increase, the probability of a
recession increases- which is counter to conventional expectations.

Economic recession prediction is an area of interest for public and private decision makers.
For national economies, the yield spread, the difference between long-term and short-term treasury
bills, is a valuable recession forecasting tool (Estrella and Mishkin, 1996; Dueker, 1997). When
the yield spread by itself is compared with other financial variables such as stock prices, and
monetary aggregates, it tends to be the only financial variable that effectively predicts recessions
after one quarter (Estrella and Mishkin, 1998). Research by Nyberg (2010) and Kauppi and
Saikkonen (2008) show that usage of the yield spread within dynamic binary response models
outperforms standard static models in predicting future recessions.
Yield spreads have also been shown to effectively predict economic recessions for state
economies (Gauger and Schuck, 2002; Shoesmith, 2003), but there is relatively little research on
this topic for metropolitan economies. That gap in the literature is somewhat puzzling.
Historically, there is much more information available regarding national and regional economies
than there is for urban economies (Klein, 1969). Given the relative paucity of information
regarding metropolitan economies, the potential predictability of business cycle downturns for
these areas by models with minimal data requirements may provide a very useful tool to
policymakers and business analysts.
While the latter is true, metropolitan business cycle indices (BCIs) are not widely available.
This study takes advantage of previously published BCIs for nine urban economies located within
the state of Texas. Those indices are compiled using a well-known methodology involving
Page 10
Kalman filtering and dynamic single-factor analysis (Stock and Watson, 1991). The indices are
maintained and updated by the Federal Reserve Bank of Dallas. As coincident indicators, these
BCIs provide gauges of current economic conditions for each of the geographic areas monitored
(FRBD, 2018). This study employs those indices for the five largest urban economies in Texas,
the four largest metropolitan areas along the Texas-Mexico border, as well as the regional BCI
estimated for the Texas state economy.
To examine metropolitan BCI downturn predictability, the study uses yield spreads plus
some other economic indicators that are potentially related to business cycle developments across
Texas. Economic conditions in Mexico have been shown to affect border regions of Texas
(Fullerton et al., 2017). Accordingly, a peso/dollar real exchange rate and a yield spread for
Mexico are also included in the sample. Because energy activities influence economic conditions
in many regions of Texas (Lee, 2015), the sample also includes the prices of West Texas
Intermediate crude oil. Parameter estimation is carried out using a dynamic probit methodology
(Ng, 2012).
Subsequent sections of the paper are as follows. The next section provides a brief overview
of related studies. Section three describes the methodological framework and data employed.
Section four provides an empirical analysis. Section five summarizes principal results and
implications for future research.
Page 11
Previous research examines what information the term structures for U.S. Treasury bill
interest rates contain about future economic conditions in national economies. Research indicates
that longer-term Treasury bill maturities have significant predictive power for future changes in
inflation (Mishkin 1990). The yield spread, the difference between long-term and short-term
treasury bills, has been found to serve as a valuable recession forecasting tool. The yield spread
tends to outperform other common recession indicators for a period of two to six quarters in the
future (Estrella and Mishkin 1996). In further research, the yield spread by itself tends to be the
only economic variable that reliably predicts recessions after one quarter (Estrella and Mishkin
1998).
Other research explores the ability yield spreads to predict future economic conditions in
developing economies. Gonzalez, Spencer and Walz (2000) determine that Mexican yield spreads
have significant forecasting ability for inflation and real growth. Interestingly, the U.S. and Euro
area yield curves contain information about future inflation and growth in emerging economies.
That especially holds true for countries with currency exchange rates that are pegged to the U.S.
dollar (Mehl 2009). Both studies indicate that the yield curve in emerging economies also contain
information about future inflation and growth.
A substantial volume of recession predictability utilizing yield curves has been conducted
for national economies. A smaller number of studies have been examined this topic for state and
regional economies. One such study finds that yield spreads can forecast multi-state regional
economic downturns, but the effectiveness of recession prediction varies according to regional
Page 12
economic structures (Gauger and Schuck 2002). Another study successfully modeled recessions
in 34 of the 50 state economies in the United States in statistically reliable manners (Shoesmith
2003).
Forecasting economic conditions in U.S.-Mexico border regions is a unique challenge
because cross-border economic relationships affect metropolitan business cycles (Fullerton 2001).
Those commercial and industrial ties include retail sector “exports,” health sector tourism, as well
as supply chain linked manufacturing, transportation, and warehousing activities (Phillips and
2008). Similarly, energy sector fluctuations are likely to play outsized roles in the business
cycle that characterizes urban economic conditions in places like Houston. Consequently, the
inclusion of variables that reflect those types of considerations may augment the information
provided by yield spreads.
When available, BCIs provide useful means for understanding prevailing states of national,
regional, or metropolitan economies. Stock and Watson (1991) develops a widely used BCI
methodology known as dynamic single-index factor modeling that employs Kalman filters. This
methodology develops BCIs under the assumption that the co-movements of key economic
indicators are influenced by a common underlying, unobservable factor. This approach has been
used to generate BCIs for various geographic regions. Among others, the latter include Texas
(Phillips 2005), Midland-Odessa (Downs and Fullerton 2017), Lubbock (Fullerton and Subia
2017), plus border urban economies in Texas (Phillips and Cañas 2008). Regional BCIs provide
fairly up to date gauges of whether the economies analyzed are expanding or contracting.
Page 13
A common approach to predicting the onset of economic contractions is to use binary
recession indicators as dependent variables. Various studies indicate that the slope of the yield
curve is the most reliable recession predictor (Dueker 1997). Incorporating lags of the binary
recession indicators in the equation specifications has been found to significantly increase the
predictive power of business downturn probit models (Kauppi and Saikkonen 2008; Nyberg 2010).
To analyze metropolitan BCI downturn predictability, this study utilizes yield spreads from the
U.S. and Mexico, plus other regionally relevant economic variables, with parameter estimation
carried out using a dynamic probit methodology. Dynamic and dynamic autoregressive probit
models have been found to perform well in this context (Ng 2012; Fullerton et al. 2017).
Regional BCI modeling efforts may benefit from the inclusion of other variables that
augment the information contained in the yield spread. For the border metropolitan economies,
Mexican yield spreads and peso/dollar currency exchange rates are likely to help predict BCI
downturns because economic condition in Mexico also affect the business conditions on the north
side of the boundary (Fullerton 2001; Fullerton et al. 2017). Oil prices are a useful indicator for
predicting business cycle downturns in economies with substantial energy activities (Lee 2015).
For example, in the petroleum driven economy of Midland-Odessa, oil price fluctuations tend to
correspond with similar shifts in local BCIs (Downs and Fullerton 2017).
The objective of this study is to develop probit downturn models for the five largest urban
economies in Texas, the four largest metropolitan areas along the Texas-Mexico border, as well as
the Texas state economy. The five largest urban economies in Texas are Austin-Round Rock,
Dallas-Plano-Irving, Fort Worth-Arlington, Houston-The Woodlands-Sugarland, and San
Page 14
Antonio-New Braunfels. The four largest metropolitan areas along the Texas-Mexico border are
Brownsville-Harlingen, El Paso, Laredo, McAllen-Edinburg-Mission.
Page 15
Probit analysis is used to quantify the probability of recessions in a particular time period.
This approach has been used to model business cycle contractions in multiple geographies. A
static probit model can be written as follows:
(1) Pr(Yt = 1) = F(β0 + β1Xt-k)
In Equation (1), Pr is the probability of an existing recession (Yt = 1 if a recession is underway at
time t, 0 if not), Xt−k is an explanatory variable at time t−k, β0 and β1 are parameters to be estimated,
and F represents the cumulative normal distribution function.
One drawback of the static model is that it does not take advantage of autocorrelated
information potentially embedded within the binary recession indicator. In such cases, dynamic
probit model specifications take into account prior states of the economy by including a lag of the
dependent variable as shown in Equation (2).
(2) Pr(Yt = 1) = F(β0 + β1Xt-k + β2Yt-m)
Dueker (1997) argues that the dynamic version of the probit model is better suited to
handling problems such as serial correlation that frequently arise in the context of time-series
modelling. Along those lines, Kauppi and Saikkonen (2008) find that dynamic probit models tend
to outperform static specifications for predicting national economic downturns in the United
Page 16
States. The model in Equation (2) can be further augmented by introducing additional explanatory
variables. Standard selection criteria such as pseudo-R2 statistics can be used to identify which
lags of candidate explanatory variables to include in an equation (Nyberg 2010).
To help select an estimated equation functional form, the pseudo-R2 metric developed by
Estrella (1998) is employed. The metric is calculated as shown below.
(3) Adjusted Pseudo - R2 = 1 – (𝐿𝑢
𝐿𝑐)−(
2𝑛)𝐿𝑐
In Equation (3), Lu is the unconstrained maximum value of the log-likelihood, Lc is the
constrained maximum value of the log-likelihood assuming all coefficients except the constant are
zero, and n is the sample size. Standard diagnostic statistics such the t-statistic are also utilized.
The modelling framework employed in this study analyzes probabilities of BCI downturns
for selected urban economies located in Texas as functions of yield-spreads as well as other
regional and macroeconomic variables. This study employs business cycle indices for the five
largest economies in Texas, the four largest metropolitan areas along the Texas-Mexico border, as
well as a regional BCI estimated for the Texas state economy. The other regional and
macroeconomic variables are included based on characteristics of the economies being analyzed.
The five largest economies in Texas all engage in energy activities or are greatly affected
by energy prices (FRBD 2014). As noted above, oil prices can help predict business cycle
fluctuations in economies with substantial energy activities (Lee 2015). Accordingly, West Texas
Page 17
Intermediate oil prices are included as part of the sample data collected for those five urban
economies.
In the four largest metropolitan economies along the Texas-Mexico border, this study
utilizes a framework similar to that outlined by Fullerton (2001). In that study, border region
economic performance is modelled as a function of both national and international variables.
Subsequent studies have confirmed that the peso/dollar exchange rate strongly influences business
activity along the border (Patrick and Renforth 1996; Coronado and Phillips 2007; Niño et al.
2015). Yield spreads for the United States and Mexico are also included in the specifications for
each of these border economies.
The dichotomous dependent variables identify downturns in each metropolitan economy.
According to Klein and Moore (1983), the binary variables are constructed using monthly
frequency regional business cycle index values. In all nine economies, the binary dependent
variable is defined by shifts in the business cycles indices. If there is a recession, the binary
dependent variable for that specific month is equal to one. If there is not a recession, this variable
is equal to zero. For purposes of this study, a recession is defined as six consecutive months (or
more) of negative growth in a business cycle index. An economic contraction ends after six
consecutive months of positive growth in a business cycle index.
The United States yield spread is calculated as the 10-year Treasury bond rate minus the
3-month Treasury bill rate. All United States interest rate data are from the Federal Reserve Bank
of St. Louis (FRED 2015). The yield spread of Mexico is calculated as the 1-year Treasury bill
Page 18
rate minus the 28-day Treasury bill rate (CETES). All Mexican interest rate data are from the
central bank of Mexico (BM 2018a). This study utilizes the above Mexican yield spread and a
peso/dollar (MXN/USD) real exchange rate index because economic conditions in Mexico
sometimes have pronounced impacts on the business cycles of the United States border cities (BM
2018b; Phillips and Cañas 2008). These international economic variables are important for this
research because the cities selected for this study and their cross-border counterparts in Mexico
share a variety of commercial and industrial linkages. The dependent variable takes a lag of one
in order to capture potential autocorrelation structures of the dependent variables (Ng 2012).
Additionally, experimentation is also conducted with an alternate lag structure of three months that
Dueker (1997) posits as the minimum recognition lag time for recessions.
Three different specifications employing the dynamic probit framework are proposed.
Equation (4) is used for the five largest urban economies in Texas. Equation (5) is employed for
the four border metropolitan economies. Equation (6) is utilized for the Texas state business cycle.
(4) Pr(Yt = 1) = F(β0 + β1USSPt-k + β2WTIt-h + β3Yt-m + εt)
(5) Pr(Yt = 1) = F(β0 + β1USSPt-k + β2MXSPt-h + β3REXRt-i + β4Yt-m + εt)
(6) Pr(Yt = 1) = F(β0 + β1USSPt-k + β2MXSPt-h + β3REXRt-i + β4WTIt-j + β5Yt-m + εt)

Table 1 summarizes the hypothesized relationships between the recession indicator, Y, and
each of the explanatory variables. In Equations (4) through (6), USSP is the United States yield
spread, WTI is the monthly West Texas Intermediate Crude Oil Spot Price in dollars per barrel,
Yt−m is a the binary dependent variable with a lag of m months, MXSP is the yield spread for
Mexico, and REXR is the inflation adjusted peso/dollar exchange rate index. The corresponding
model is estimated for each of the metropolitan economies mentioned above in the previous
section.
Equation (4) is used to examine whether the yield spreads and the spot prices of WTI oil
can help predict recessions in the five largest Texas metropolitan economies. A decrease in the
United States yield spread, which results from higher short-term interest rates and/or lower long-
term rates, is hypothesized to increase the probability that a recession will occur in future quarters
(this is also posited for Equations (5) and (6)). That is because high short-term interest rates are
often associated with contractionary monetary policy and lower long-term rates may reflect
expectations of an economic slowdown in coming years (Dueker 1997). A decrease in the spot
prices of WTI oil is hypothesized to increase the probability a recession will occur in future
quarters. That is because low oil prices dampen growth within the energy sector which hurts the
Texas economy as a whole. A value of 1 in the binary dependent variable is hypothesized to be
associated with an increased probability that a recession will occur in future quarters.
Equation (5) is used to examine whether the yield spreads and the real exchange rate index
can help predict recessions in the four largest metropolitan economies along the Texas-Mexico
border economies comprised in the sub-sample. For similar reasons to the United States yield
Page 20
spread, the yield spread for Mexico is expected to have an inverse relationship with the probability
of recession. Economic slowdowns in Mexico may coincide with downturns in cities on the north
side of the border for a variety of reasons. First, retail sectors in many United States border cities
rely on a steady influx of Mexican shoppers. Those sales tend to decline when such shoppers
reduce consumption, as typically occurs when Mexico faces a recession (Coronado and Phillips
2007; Phillips and Cañas 2008). Other border region economic sectors such as freight
transportation, wholesale trade, and financial services conduct business with manufacturers
located in Mexico (Cañas et al. 2013). Thus, a higher probability of recession in Mexico, as
signaled by a flattening or inversion of that country’s yield curve, is hypothesized to increase the
probability of recession on the north side of the border.
The impacts of real exchange rate on border city economies is ambiguous. Some prior
research suggests that peso depreciations can have strong adverse impacts on retail sectors in the
United States border cities (Patrick and Renforth 1996). However, peso depreciations also tend to
stimulate export-processing activity in Mexican border cities, which may help fuel economic
activity on the north side of the border (Niño et al. 2015). If a real depreciation of the peso lowers
the probability of recession for any of the border economies examined, then the exchange rate
coefficients will be negative. The converse will occur if peso weakness increases the likelihood
of a business cycle downturn.
Equation (6) is used to examine whether the yield spreads, the real exchange rate index,
and the spot prices of WTI oil can help predict recessions for the Texas state economy. The
impacts of fluctuations in these variables on the metropolitan economies in the sample are
Page 21
discussed above. Equation (6) reflects many aspects of the modern Texas economy, regionally,
nationally, and internationally.

Chapter 4: Empirical Analysis
Equations with varying specifications are estimated for each economy. The final
specifications are selected by taking into consideration pseudo-R2 values, lag length information
criteria, coefficient statistical significance, and other statistical diagnostic tools (Gauger and
Schunk 2002; Nyberg 2010). Initial dependent variable lag specifications of one month are sub-
optimal when compared to the alternate dynamic lag specification of three months. Results for the
initial dynamic lag specification of one month are published in Appendix Tables 7.A through 8.B.
Sample data employed are from January 1991 to May 2018, a span of about 27 years. Primary
In general, Equations 4 through 6, outlined in the previous section, deliver favorable
estimation results. Given the geographic location of Laredo on the Eagle Ford shale formation, an
alternate model is specified by including the West Texas intermediate oil price as an explanatory
variable. Fort Worth, Laredo, and the Texas economies are the only economies that deviate from
the general equation specifications outlined in the previous section. The coefficient sign for West
Texas intermediate oil prices in Fort Worth and Texas were positive which runs counter to
conventional wisdom. It is, therefore, removed from the model specification for those economies.
A positive coefficient for West Texas intermediate oil prices also results when it is included
in equations estimated for Laredo. The version summarized in Table 2 exhibits much better
statistical traits than other specifications, as well as more realistic coefficients for the other
Page 23
regressors. Alternative specification outcomes for all of the regions analyzed are included in the
appendix materials.

from the USSP measure calculated as the difference between the 10-year Treasury bond rate and
the 3-month Treasury bill rate. The lead times for MXSP align closely with those reported in other
studies (Fullerton 2017; and Reyna-Cerecero et al. 2008).
Page 27
The results in Table 2 indicate that real depreciation of the peso against the dollar decreases
the probability of a recession in all four of the border economies. As previously stated, peso
depreciations tend to stimulate export-processing activity in northern border municipalities in
Mexico (Coronado et al. 2004; Fullerton et al. 2004; Canas et al. 2007; Niño et al. 2015). That
generally leads to increased economic activity in the adjacent metropolitan areas on the northern
side of the international boundary (Hanson 1996; Varella-Mollick et al. 2006; Canas et al. 2013).
The negative REX coefficients provide additional evidence along those same lines.
Nearly all of the West Texas intermediate spot oil price parameter estimates for the
metropolitan economies are negative. The exception is the WTI coefficient estimated for Laredo.
As stated at the beginning of this section, oil prices are included in the specification of this border
economy because of its presence on the Eagle Ford Shale formation. The positive parameter is
puzzling. As will be discussed below, Laredo has a very high concentration of employment in
transportation and warehousing. Across the border, and closely linked to that segment of the
Laredo metropolitan economy, are large manufacturing sectors in both Monterrey and Nuevo
Laredo. Transportation and manufacturing are energy intensive sectors and that may be what leads
to the positive correlation between oil price hikes and recessions in the former Rio Grande
Republic. As more data become available, additional research appears warranted.
Prior research indicates that the yield spread has relatively high predictive power in regions
that are heavily dominated by interest-sensitive employment sectors such as manufacturing and
construction (Gauger and Schunk 2002). Shoesmith (2003) confirms that the use of interest-rate
spreads to predict future state recessions is more effective in manufacturing-intensive states.
Page 28
Fullerton et al. (2017) also finds evidence that the yield spread helps predict employment losses in
southern border economies in the United States. Those regions typically have relatively high
concentrations of interest-rate sensitive sectors such as construction, manufacturing,
transportation, and warehousing.
In order to see if this pattern holds true for the economies analyzed in this study, formal
log-likelihood ratio test outcomes are juxtaposed against corresponding percentages of
employment in construction, manufacturing, and transportation. To calculate the log-likelihood
statistic, restricted versions of Equations (4) through (6) are specified without either of the yield
spread variables. Then, using the unrestricted log-likelihoods displayed in Tables 2, 4, and 6 plus
the restricted equation log-likelihoods, log likelihood ratio test statistics are calculated. Table 8
reports those results. When the log-likelihood ratio statistic is larger than the corresponding chi-
squared critical value, the null hypothesis is rejected and model performance is improved by the
inclusion of the yield spread variables. If the pattern described in the preceding paragraph is true,
economies with the largest market shares of the interest-rate sensitive jobs should correspond with
the largest log likelihood ratio test statistics.

Figure 10: Texas (State) Actual and Fitted Values
Page 35
The dynamic probit models estimated for each Texas economy in the sample provide
generally adequate information regarding the probability of business cycle downturns. In most
cases, when the predicted probabilities exceed 0.5 (50 percent), recessions occur. In contrast, the
predicted probabilities tend to stay below 0.5 when the economies are growing. The recession
forecasts do have some missteps. In 2000, two of the equation simulations generated false signals
for slumps that never materialized. Those false signals are for the Brownsville border economy
and the Dallas metropolitan economy.
Page 36
Regional and metropolitan business cycle indices are not widely available, but several
variables are estimated for Texas and nine of the largest urban economies in that state. Modeling
and predicting recessions in Texas, however, offers a special challenge. The state is so large that
the various urban economies located in Texas exhibit unique business cycle idiosyncrasies. Given
the importance of international trade in Texas, many urban economies in the state are affected by
domestic and international factors. This study attempts to allow for these factors using domestic
and foreign yield spreads, a real peso per dollar exchange rate, West Texas Intermediate oil prices,
and a dynamic lag variable. To date, there have been few economic downturn prediction efforts
conducted for metropolitan economies. Among the regional business cycle studies that have been
completed, yield spreads have been shown to reliably predict recessions.
The United States yield spread is also found to predict slumps in all of the economies
analyzed in this study. Confirming relatively important cross-border industrial and commercial
linkages, Mexico yield spread is found to help anticipate economic contractions for all four border
economies as well as for the Texas state economy. Unexpectedly, the real peso per dollar exchange
rate index is a reliable predictor of business cycle downturns for only two of the four border
economies. Somewhat surprisingly, West Texas Intermediate oil price declines help predict
economic slumps for four of the large urban economies, but not for the state as a whole. Finally,
the 3-month dynamic lag specification of three months perform better than the 1-month dynamic
lag specification, offering regional evidence that three months is the minimum recognition lag time
Page 37
for recessions. In-sample simulations indicate that the estimated models exhibit good predictive
behavior with only minimal false signal emissions.
Future research may benefit from more Mexico yield spread data. Although Mexico does
have a term structure, yields on government bonds with maturities of longer than three years only
date from 2000 forward. As more yield spread observations become available, that may contribute
better information regarding the onset of regional downturns in Texas. More broadly, metropolitan
business cycle index estimation has fairly minimal data requirements. These indices provide
useful information to policymakers and business analysts. As the procedure is extended to analyze
more regions, further research on business cycle predictability will become feasible. That should
allow clarifying the conditions under which apparent coefficient sign anomalies occur.
