Dating US business cycles with macro factors

Abstract

Latent factors estimated from panels of macroeconomic indicators are used to generate recession probabilities for the US economy. The focus is on current (rather than future) business conditions. Two macro factors are considered: (1) a dynamic factor estimated by maximum likelihood from a set of 4 monthly series; (2) the first of eight static factors estimated by principal components using a panel of 102 monthly series. Recession probabilities generated using standard probit, autoregressive probit, and Markov-switching models exhibit very different properties. Overall, a simple Markov-switching model based on the big data macro factor generates the sequence of out-of-sample class predictions that better approximates NBER recession months. Nevertheless, it is shown that the selection of the best performing model depends on the forecaster’s relative tolerance for false positives and false negatives.

Appendix A. Autoregressive probit model estimation

The regression equation for the factor-augmented autoregressive probit model is

(A.1)yt=γzt+θyt1+ϵt,

where γ=(α, δ)′ and zt=(1,h^t), and the likelihood function for the model is

(A.2)L(y|z,γ,θ,y0)=t=1T[Φ(γzt+θyt1)]yt[1Φ(γzt+θyt1)]1yt.

The implementation of the Gibbs sampler is similar to that of Dueker (1999) and Chauvet and Potter (2005, 2010). After generating initial values of the latent variable yt, the sampler proceeds as follows: (i) generate draws of the latent variable yt conditional on (γ′, θ) and the observed data; (ii) generate draws of γ′ conditional on (yt,θ) and the observed data; (iii) generate draws of θ conditional on (yt,γ) and the observed data. Prior and posterior distributions are discussed next.

A.1 Generating draws of the latent variable

Initial values of the latent variable, yt(0) for t=1, …, T, are drawn from f(yt(0)|yt1(0),yt) with y0(0)=0. Conditional on yt1 and yt, yt has a truncated normal distribution where yt0 if yt=1 and yt<0 if yt=0. The truncation imposes a sign condition on yt based on the observed value yt. Then, potential values of yt(0) are drawn from yt(0)N(γzt+θyt1(0),1). Draws are discarded if the sign condition is not satisfied.

Obtaining subsequent draws of the latent variable yt conditional on the parameters and the observed data requires the derivation of the the conditional distribution yt|yt1,yt+1. As the vector (yt+1,yt,yt1) has a joint normal distribution, the conditional distribution yt|yt1,yt+1 is also normal. Starting with (A.1) and substituting backwards for lagged y*’s on the right side, the following results can be derived:

yt=s=0t1θsγzts+s=0t1θsϵts,E(yt)=At=s=0t1θsγzts=γzt+θAt1,Var(yt)=Bt=s=0t1θ2s=1+θ2Bt1,Cov(yt,yt1)=θBt1.

The joint distribution of the vector (yt+1,yt,yt1) is then

[yt+1ytyt1]N([At+1AtAt1],[Bt+1θBtθ2Bt1BtθBt1Bt1]).

Using standard results for the multivariate normal distribution, yt|yt+1,yt1N(μ˜t,Σ˜t) for t=2, …, T−1, with truncation such that yt0 if yt=1 and yt<0 if yt=0 and

μ˜t=At+θ(BtBt1)(Bt+1θ2Bt1Bt1)1(yt+1At+1yt1At1),Σ˜t=Btθ2(BtBt1)(Bt+1θ2Bt1Bt1)1(BtBt1).

Finally, assuming y0=0,y1|y2N(μ˜1,Σ˜1), with truncation such that y10 if y1=1 and y1<0 if y1=0 and

μ˜1=A1+θB1B21(y2A2)=A1+θ1+θ2(y2A2),Σ˜1=B1θ2B1B21B1=1θ21+θ2.

Based on these results, subsequent draws of the latent variable, yt(i) for t=1, …, T, are taken from f(yt(i)|yt1(i1),yt+1(i),yt) for t=1, …, T−1 and f(yt(i)|yt1(i1),yt) for t=T where i denotes the ith cycle of the Gibbs sampler. As in Chauvet and Potter (2005, 2010), I start drawing a value of yT conditional on a value of yT1 and yT from yT(i)N(γzT+θyT1(i1),1), with truncation such that yT(i)0 if yT=1 and yT(i)<0 if yT=0. With this value of yT, I generate draws of yt for t=1, …, T−1 backwards using the results described above. Potential draws of yt are discarded if the sign condition is not satisfied.

A.2 Prior and posterior for γ

Following Albert and Chib (1993) and Dueker (1999), I use a flat non-informative prior for γ. Initial values for γ in the first cycle of the Gibbs sampler are the least squares estimates from a regression on the observed variable yt without autoregressive terms. Let Wtγ=ytθyt1, then draws of γ are generated from the multivariate normal distribution γ|y,θ,yN(γ^,(zz)1) where γ^=(zz)1zWγ.

A.3 Prior and posterior for θ

Similarly, I use a flat non-informative prior for the autoregressive parameter θ. The initial value of θ to start the Gibbs sampler is set at 0.5. Let Wtθ=ytγzt and Wty=yt1, with W1y=0. Then, potential draws of θ are generated from θ|y,γ,yN(θ^,(WyWy)1) where θ^=(WyWy)1WyWθ. Draws are discarded if the stationarity condition |θ|<1 is not satisfied.

A.4 Recession probabilities

Conditional recession probabilities are generated at each draw of the Gibbs sampler such that

(A.3)pt(i)=Φ(γ(i)zt+θ(i)yt1(i)),

where i denotes the ith cycle of the Gibbs sampler. The posterior mean probability of recession is given by

(A.4)p^t=1Ii=1Ipt(i),

where I denotes the total number of draws.

Appendix B. Data appendix

A data set of the four indicators used to estimate the dynamic factor (industrial production, real manufacturing sales, real personal income less transfer payments, and employment) corresponding to the February 2011 vintage was provided by Jeremy Piger. Real-time vintage data for the dynamic factor is from Camacho, Perez-Quiros, and Poncela (2013).

The table below lists the 102 time series included in the balanced panel. The table lists the short name of each series, the transformation applied (number of months to be lagged in parentheses), and a brief data description. All series are from FRED – St. Louis Fed –, unless the source is listed as ECON (Economagic), GFD (Global Financial Data), or AC (author’s calculation) and correspond to the February 2011 vintage. The transformation codes are: 1=no transformation; 2=first difference; 3=second difference; 4=logarithm; 5=first difference of logarithms; 6=second difference of logarithms.
