The changing international transmission of U.S. monetary policy shocks: Is there evidence of contagion effect on OECD countries

We study the changing international transmission of U.S. monetary policy shocks to 14 OECD countries over the period 1981Q1–2010Q4. The U.S. monetary policy shock is defined as unexpected change in Effective Federal Funds Rate (FFR). We use a time varying parameter factor augmented VAR approach (TVP-FAVAR) to study the EFFR shocks together with a large data set of 265, major financial, macroeconomic and trade variables for U.S., Canada, France, Germany, Italy, UK, Japan, Australia, Spain, Norway, Sweden, Switzerland, Finland and New Zealand. Our main findings are as follows. First, negative U.S. monetary policy shocks have considerable negative impact on GDP growth in the U.S., Canada, Japan and Sweden while most of the other member countries benefits. Second, the transmission to GDP growth has increased in OECD countries since the early 1980s. We also detect a more depressed GDP over medium term in the U.S., Canada, Japan, Australia, Norway and Sweden over the recent global financial crisis. Third, the size of U.S. monetary policy shocks during financial turmoil periods were unusual than normal periods and varies overtime. The financial crisis (2008–2009) is evidenced by decline in residential investment in the U.S. and propagation of this shock to Canada, Germany, Japan, Switzerland and New Zealand over the recent period. U.S. monetary policy shocks reduce share prices in most of the OECD countries; this impact is more pronounced over the turmoil period. Asset prices, interest rates and trade channel seem to play major role in propagation of monetary policy shocks.     

THE BEHAVIOR OF U.S. PUBLIC DEBT AND DEFICITS DURING THE GLOBAL FINANCIAL CRISIS

In this paper we test the sustainability of U.S. public debt for the period 1916–2012 by analyzing how the primary surplus to gross domestic product (GDP) responds to changes in the debt to GDP ratio in a time‐varying parameter model. Further, we determine the stationarity property of the debt/GDP ratio while accommodating possible breaks in the data caused by wars and economic crisis under both the null and alternative hypotheses of an endogenous unit root test. The results show that the U.S. public debt was sustainable until 2005 when the primary surplus to GDP reacted negatively to the debt/income ratio. This is further exacerbated during the global financial crisis when primary surpluses continued to fall with increased debt, thus jeopardizing the sustainability of fiscal policy. While the stationarity test shows that the U.S. fiscal debt/GDP ratio is sustainable, it fails to highlight the risk that its debt policy has been becoming unsustainable in recent years.

Non-Walrasian Labor Markets and Real Business Cycles

The standard real business cycle literature mainly focuses on Walrasian models designed to fit the U.S. institutional framework. Differences between the United States and Europe, mostly evident in the labor market, suggest that a purely Walrasian model may be inappropriate for the study of European business cycles. I present a stochastic version of the dynamic general equilibrium model of Daveri and Maffezzoli (2000, “A Numerical Approach to Fiscal Policy, Unemployment and Growth in Europe,” Econometrics and Applied Economics Working Paper 2000-4, IEP, Università Bocconi), where unemployment is generated by monopolistic unions, and calibrate it to reproduce several long-run features of the Italian and U.S. economies. This framework is then compared with an indivisible labor model built on Hansen (1985, Journal of Monetary Economics16, 309–328) and Rogerson and Wright (1988, Journal of Monetary Economics22, 501–515). I focus on the impulse response functions, the standard business cycle statistics, and the ability to reproduce the cyclical components of the main macroeconomic variables. The main results are as follows: (i) the impulse response functions of the monopoly union (MU) model show a higher degree of overall persistence; (ii) the business cycle statistics are similar; (iii) the MU model enjoys a statistically significant advantage in reproducing the Italian business cycle, but not that of the United States.

Does Intrinsic Habit Formation Actually Resolve the Equity Premium Puzzle?

G. M. Constantinides (1990, Journal of Political Economy98, 519–543) describes a simple model of intrinsic habit formation that appears to resolve the “equity premium puzzle” of R. Mehra and E. C. Prescott (1985, Journal of Monetary Economics15, 145–161). This finding is particularly important, since it has motivated a broader consideration of the implications of habit formation preferences in dynamic equilibrium models. However, consumption growth actually behaves very differently pre- and post-1948, and the explanatory power of the habit formation model is driven by the pre-1948 data. Using data from 1949 to 2000, constructed in a manner comparable to R. Mehra and E. C. Prescott, I demonstrate that intrinsic habit cannot rationalize the unconditional moments of discrete consumption and real asset returns with values of the risk aversion coefficient that are less than four times larger than the values found by G. M. Constantinides for any feasible calibration of the model. Journal of Economic Literature Classification Numbers: E21, G12.     

The Equivalence of Wage and Price Staggering in Monetary Business Cycle Models

This paper considers the persistence puzzle documented by V. Chari, P. Kehoe, and E. McGratten (2000, Econometrica68, 1151–1179). Specifically, it addresses a claim by T. Andersen (1998, European Economic Review42, 593–603) and K. Huang and Z. Liu (1999, “Staggered Contracts and Business Cycle, Persistence,” Federal Reserve Bank of Minneapolis Discussion Paper 127) that staggered-wage models are better able to generate persistent real responses to monetary shocks than are staggered-price models. The paper argues that this result hinges on the assumption of homogeneous factor markets and shows that by assuming firm-specific factor inputs the staggered-price model is as capable as the staggered-wage model is of generating persistent real responses to monetary shocks.

Price Level Determinacy under a Pure Interest Rate Peg

In this article we reexamine a famous result by T. J. Sargent and N. Wallace (1975, Journal of Political Economy83, 241–254) according to which a “pure interest rate peg” leads to nominal price indeterminacy. We use P. Weil's (1991, International Economic Review32, 37–53) generalization of the Sidrauski–Brock model, where arrival of new “generations” of infinitely lived agents is allowed, and we obtain the following results: (i) Nominal indeterminacy holds in the traditional Sidrauski–Brock framework; (ii) This nominal indeterminacy disappears as soon as new generations arrive in time, via some rigorous version of Patinkin's “real balance effect”; (iii) A multiplicity of solutions may still remain, but full determinacy occurs in some cases, depending notably on fiscal policy or the distribution of endowments in time.

Endogenous Cycles and Growth with Indivisible Technological Developments

When large, discrete technological improvements require the accumulation of research or infrastructural investment over time, growth paths display cyclical patterns even in the absence of any shocks. Particularly interesting equilibrium features of these cycles include declines in output and asymmetries in the cyclic patterns displayed during expansions and recessions.Journal of Economic LiteratureClassification Numbers: E22, E32, O41.     

Exchange Rate Determination: An Application of a Monetary Model for Brazil

The goal of this paper is to test a variant of the monetary exchange rate determination model, described by Obstfeld and Rogoff (1996), for the Brazilian economy in the recent period. The model starts with the Cagan (The Journal of Political Economy, 66(4):303–328, 1958) money demand, which is complemented by the hypotheses of purchase power parity (PPP) and uncovered interest parity (UIP). We used monthly data of exchange rate, GDP, interest rate for Brazil, and U.S. interest rate and inflation as proxies for international variables. We applied cointegration tests to identify a long run relationship among the variables. The estimated error correction model offers an exchange rate determination model in the short run. Due to potential endogeneity of some variables, GMM was applied to estimate a long-run model of exchange rate determination. The forecasting results of both estimatives were compared with a random walk approach. The results point to the existence of a long and short run equilibrium Real/dollar exchange rate using the structural model, which may be the achievement of this paper.     

Understanding the Effects of a Shock to Government Purchases

This paper investigates the consequences of an exogenous increase in U.S. government purchases. We find that in response to such a shock, employment, output, and nonresidential investment rise, while real wages, residential investment, and consumption expenditures fall. The paper argues that a simple variant of the neoclassical growth model which distinguishes between nonresidential and residential investment is consistent with this evidence.Journal of Economic LiteratureClassification Numbers: E1, E6.     

Investigating business cycle asymmetry for the G7 countries: Evidence from over a century of data

In this paper we test for asymmetric behaviour of business cycles for the G7 countries, using the entropy-based test for asymmetry suggested by Racine and Maasoumi [Racine, J.S., & Maasoumi, E. (in press-a). A versatile and robust metric entropy test of time-reversibility, and other hypotheses, Journal of Econometrics; Racine, J.S., & Maasoumi, E. (in press-b). A robust entropy based test for asymmetry. Econometric Reviews.]. We find overwhelming evidence of symmetry. In only 14% of the cases, we find some evidence of asymmetric behaviour of GDP and per capita GDP. More importantly, the period marked by the flexible exchange rate regime, over which much of the empirical work for the G7 countries has been conducted, evidence suggests that the two GDP series are symmetric.     

The Phillips Curve and Optimal Policy in a Structural Signal Extraction Model

We study a monetary economy subject to “signal extraction” problems, and investigate within that framework the positive and normative aspects of monetary policy. As in Lucas (1972, Journal of Economic Theory,4, 103–124; 1973, American Economic Review, 63, 326–334), imperfect signal perception generates macroeconomic correlations similar to those found in the “Phillips curve” literature. Moving to normative aspects, we find that, when aggregate shocks are present, traditional nonactivist policies do not permit reaching the first best, and that an intelligent activist policy always leads to better outcomes. The specific characteristics and effectiveness of this optimal policy also depend crucially on the problem of signal extraction. Journal of Economic Literature Classification Number: E5.     

On the Distributional Effects of Social Security Reform

How will the distribution of welfare, consumption, and leisure across households be affected by social security reform? This paper addresses this question for social security reforms with a two-tier structure by comparing steady states under a realistic version of the current U.S. system and under the two-tier system. The first tier is a mandatory, defined-contribution pension offering a retirement annuity proportional to the value of taxes paid, whereas the second tier guarantees a minimum retirement income. Our findings, which are summarized in the Introduction, do not in general favor the implementation of pay-as-you go versions of the two-tier system for the U.S. economy.

Output gains from accelerating core inflation

Previous research finds that the analysis of sacrifice ratios–namely, identifying disinflation episodes, calculating the sacrifice ratio, and looking at its determinants–changes substantially when one moves from headline to core inflation. This paper examines whether similar findings are obtained when examining benefice ratios, and we find arguably even greater differences. Specifically, we see that headline inflation identifies far more inflationary episodes since the 1990s than core inflation does. Furthermore, Jordan’s (1997) argument that the speed of inflation is a negative and significant determinant of benefice ratios does not hold when we move from headline to core inflation, both within the U.S. and also across the OECD. We also find strong evidence that the initial level of GDP at the onset of an inflationary episode matters. In particular, output gains from accelerating inflation appear only to be beneficial for OECD countries that start with a low level of GDP. Conversely, countries that start with a high level of GDP should not pursue additional output gains from allowing a rise in inflation.     

Fertility Decisions and Gender Differences in Labor Turnover, Employment, and Wages

A striking observation of the U.S. and other labor markets is the weak position of women in terms of job attachment, employment, and earnings relative to men. We develop a model of fertility and labor market decisions to study the impact of fertility on gender differences in labor turnover, employment, and wages. In our framework, individuals search for jobs and accumulate general (experience) and specific (tenure) human capital when they work. They can also increase their wage by moving to a job of higher quality. Labor market decisions (e.g., job acceptance and job mobility) may differ across genders: females that give birth may decide to interrupt their labor market attachment in order to enjoy the value of staying at home with their children. The model economy is successfully calibrated to match aggregate statistics in terms of fertility, employment, and wages. We find that fertility decisions generate important gender differences in turnover rates, with long lasting effects in employment and wages. These differences in labor turnover account for almost all the U.S. gender wage gap that is attributed to labor market experience by Blau and Kahn (2000, Journal of Labor Economics15(1), 1–42). The model also implies a very small role of tenure capital in accounting for wage differences between males and females (gender gap), and between females with and without children (family gap).

Mutual Insurance,Individual Savings,and Limited Commitment

We examine a dynamic model of mutual insurance when households can also engage in self-insurance by storage. We assume that there is no enforcement mechanism, so that any insurance is informal and must be self-enforcing. We show that consumption allocations satisfy a modified Euler condition and that an enhanced storage technology can either improve or diminish welfare. Furthermore we show that the ex ante transfers introduced into dynamic informal insurance models recently by Gauthier et al. (Gauthier, C., Poitevin, M., and González, P. (1997). Journal of Economic Theory76, 106–144) are only used here in the first period, with the role of ex ante transfers being replaced by differential individual storage.

WHAT IT TAKES TO SOLVE THE U.S. GOVERNMENT DEFICIT PROBLEM

This paper uses a structural multi‐country macroeconometric model to estimate the size of the decrease in transfer payments (or tax expenditures) needed to stabilize the U.S. government debt/gross domestic product (GDP) ratio. It takes into account endogenous effects of changes in fiscal policy on the economy and in turn the effect of changes in the economy on the deficit. A base run is first obtained for the 2013:1–2022:4 period in which there are no major changes in U.S. fiscal policy. This results in an ever increasing debt/GDP ratio. Then transfer payments are decreased by an amount sufficient to stabilize the long‐run debt/GDP ratio. The results show that transfer payments need to be decreased by 2% of GDP from the base run, which over the 10 years is $3.2 trillion in 2005 dollars and $4.8 trillion in current dollars. The real output loss is 1.1% of baseline GDP. Monetary policy helps keep the loss down, but it is not powerful enough in the model to eliminate all of the loss. The estimates are robust to a base run with less inflation and to one with less expansion. (JEL E17)     

On Forward Induction and Evolutionary and Strategic Stability

We analyze which normal form solution concepts capture the notion of forward induction, as defined by E. van Damme (1989, J. Econ. Theory48, 476-496) in the class of generic two player normal form games preceded by an outside option. We find that none of the known strategic stability concepts (including Mertens stable sets and hyperstable sets) capture this form of forward induction. On the other hand, we show that the evolutionary concept of EES set (J. Swinkels, 1992, J. Econ. Theory57, 306-332) is always consistent with forward induction.

Methodological Procedure for Estimating Brazilian Quarterly GDP Series

This paper presents a methodology for estimating the Brazilian GDP quarterly series in the period between 1960–1996. Firstly, an Engle–Granger’s static equation is estimated using GDP yearly data and GDP-related variables. The estimated coefficients from this regression are then used to obtain a first estimation of the quarterly GDP, with unavoidable measurement errors. The subsequent step is entirely based on benchmarking models estimated within a state space framework and consists in improving the preliminary GDP estimation in order to both eliminate as much as possible the measurement error and that the sum of the quarterly values matches the annual GDP.

A variable P value rolling Grey forecasting model for Taiwan semiconductor industry production

The semiconductor industry plays an important role in Taiwan's economy. In this paper, we constructed a rolling Grey forecasting model (RGM) to predict Taiwan's annual semiconductor production. The univariate Grey forecasting model (GM) makes forecast of a time series of data without considering possible correlation with any leading indicators. Interestingly, within the RGM there is a constant, P value, which was customarily set to 0.5. We hypothesized that making the P value a variable of time could generate more accurate forecasts. It was expected that the annual semiconductor production in Taiwan should be closely tied with U.S. demand. Hence, we let the P value be determined by the yearly percent change in real gross domestic product (GDP) by U.S. manufacturing industry. This variable P value RGM generated better forecasts than the fixed P value RGM. Nevertheless, the yearly percent change in real GDP by U.S. manufacturing industry is reported after a year ends. It cannot serve as a leading indicator for the same year's U.S. demand. We found out that the correlation between the yearly survey of anticipated industrial production growth rates in Taiwan and the yearly percent changes in real GDP by U.S. manufacturing industry has a correlation coefficient of 0.96. Therefore, we used the former to determine the P value in the RGM, which generated very accurate forecasts.     

Privatizing Social Security in the United States—Comparing the Options

This paper uses a new version of the Auerbach–Kotlikoff model to consider alternative ways to privatize the U.S. Social Security System. The new model incorporates intra- and intergenerational heterogeneity and is closely calibrated to U.S. fiscal institutions. Three privatization issues are considered: financing the transition, participation rules, and progressivity. As shown, Social Security's privatization can substantially raise long-run living standards. But these gains come at the cost of welfare losses to transition generations and take a long time to materialize. The long-run poor have much to gain from privatization even absent an explicit redistribution mechanism. Finally, privatizations that give initial workers the option of remaining in the current system have particularly low transition costs and particularly favorable macroeconomic consequences.
