Liquidity,assets and business cycles

The objective here is to evaluate the quantitative importance of financial frictions in business cycles. The analysis shows that a negative financial shock can cause aggregate investment, employment and consumption to fall with output. Despite this realistic comovement among macro quantities, a negative financial shock generates an equity price boom as the shock tightens firms׳ financing constraint. This counterfactual response of the equity price is robust to a wide range of variations in how financial frictions are modeled and whether financial shocks affect asset liquidity or firms׳ collateral constraints. Some possible resolutions to this puzzle are discussed.     

Correlations,business cycles and integration

Correlations and the integration of capital markets impact upon portfolio diversification. The key research question addressed in this paper is whether and to what extent business cycles and financial deregulation affect correlations and integration between the Australian and US markets. In summary, four major themes can be detected in our findings. First, correlations between the Australian and US markets are at their highest when the US is in a contractionary phase. Secondly, we are more likely to conclude that the markets are integrated in the expansionary phase of business cycles. Thirdly, we are more likely to conclude that the markets are segmented in the contractionary phase of the business cycles. Finally, we are more likely to conclude that markets are segmented prior to deregulation and integrated in the post financial deregulation period.     

Trade wedges,inventories, and international business cycles

The large, persistent fluctuations in international trade that cannot be explained in standard models by changes in expenditures and relative prices are often attributed to trade wedges. We show that these trade wedges can reflect the decisions of importers to change their inventory holdings. We find that a two-country model of international business cycles with an inventory management decision can generate trade flows and wedges consistent with the data. Moreover, matching trade flows alters the international transmission of business cycles. Specifically, real net exports become countercyclical and consumption is less correlated across countries than in standard models. We also show that ignoring inventories as a source of trade wedges substantially overstates the role of trade wedges in business cycle fluctuations.     

Political regimes,business cycles,seasonalities, and returns

This paper provides a method for testing for regime differences when regimes are long-lasting. Standard testing procedures are generally inappropriate because regime persistence causes a spurious regression problem – a problem that has led to incorrect inference in a broad range of studies involving regimes representing political, business, and seasonal cycles. The paper outlines analytically how standard estimators can be adjusted for regime dummy variable persistence. While the adjustments are helpful asymptotically, spurious regression remains a problem in small samples and must be addressed using simulation or bootstrap procedures. We provide a simulation procedure for testing hypotheses in situations where an independent variable in a time-series regression is a persistent regime dummy variable. We also develop a procedure for testing hypotheses in situations where the dependent variable has similar properties.     

Time series decomposition and measurement of business cycles, trends and growth cycles

A study of business cycles does not require trend estimation and elimination, but a study of growth cycles does. Major cyclical slowdowns and speedups deserve to be analyzed, but the needed time series decomposition presents difficult problems, mainly because trends and cycles influence each other. We compare cyclical movements in levels, deviations from trend, and smoothed growth rates for both the quarterly real GDP and the monthly U.S. Coincident Index—using the phase average trend (PAT). Then we compare alternative trend estimates, deterministic and stochastic, linear and nonlinear, and the corresponding series of deviations from these trends. We discuss how the resulting estimates differ for U.S. growth cycles in the post-World War II period. The results of PAT show great similarity to the results obtained with the Hodrick-Prescott, local linear trend, band-pass filtering methods.     

News shocks and business cycles

This paper proposes and implements a novel structural VAR approach to the identification of news shocks about future technology. The news shock is identified as the shock orthogonal to the innovation in current utilization-adjusted TFP that best explains variation in future TFP. A favorable news shock leads to an increase in consumption and decreases in output, hours, and investment on impact - more suggestive of standard DSGE models than of recent extensions designed to generate news-driven business cycles. Though news shocks account for a significant fraction of output fluctuations at medium frequencies, they contribute little to our understanding of recessions.     

Finance and international business cycles

Business cycles are more correlated among countries that have similar financial structures. We first document this empirical regularity using OECD data, and then build a two-country DSGE model with financial frictions that replicates it. Alternative monetary policy regimes and parameter values are explored. Output co-movements increase when the countries involved are linked by a credible exchange rate peg and when they open up to trade; they decrease when their financial openness increases. The model also accounts for a number of stylized facts of international business cycles, such as the positive international correlation of output, investment and employment.     

Investment shocks and business cycles

The origins of business cycles are still controversial among macroeconomists. This paper contributes to this debate by studying the driving forces of fluctuations in an estimated new neoclassical synthesis model of the U.S. economy. In this model, most of the variability of output and hours at business cycle frequencies is due to shocks to the marginal efficiency of investment. Imperfect competition and, to a lesser extent, technological frictions are the key to their transmission. Although labor supply shocks explain a large fraction of the fluctuations in hours at very low frequencies, they are irrelevant over the business cycle. This finding is important because the microfoundations of these disturbances are widely regarded as unappealing.     

Capital structure and business cycles

This study investigates the relationship between business cycles and capital structure. Specifically, it extends the work of Lemmon et al. (2008) , by incorporating the effect of four different stages of the business cycle – peak, contraction, trough and expansion – on the relative importance of the unobserved permanent component of the capital structure. Results indicate that business cycles play an important role in explaining the unobserved permanent component of leverage ratios after controlling for firm fixed effects. In particular, the model becomes much stronger in explaining the variation in leverage ratios after accounting for business cycle phases.     

Money and economic activity,inventories and business cycles

Incomplete information is a necessary condition for any real effects produced by monetary impulses. An alternative to the local-global inference problem is explored in this paper. Agents are confronted with permanent and transitory shocks. Even with full knowledge about the stochastic structure their best perception at any particular time will usually be erroneous. Prices for each period are set at the beginning of the period on the basis of market conditions. The realization of the shock process thus creates a short-run ‘disequilibrium’ absorbed by inventory adjustments. This adjustment translates perceived transitory monetary shocks into serially correlated output movements. The analysis proceeds within the context of rational expectations It offers a generalization of equilibrium analysis in two respects. Prices are always in equilibrium relative to perceived conditions, but they do not reflect all ongoing shocks. Quantity adjustments reflect the perceived transitory shocks. The framework used involves moreover a stock-flow interaction operated by inventory adjustments. The stock-flow interaction imposes at any time a future expected adjustment path (for price-level and quantities) to the system's unique stock equilibrium. A major implication of the analysis resolves a puzzle experienced in a recent paper by Robert Hall. It reconciles intertemporal substitution with lagged effects of monetary impulses. It also reconciles small and inconclusive cyclic movements in real wages with the occurrence of production function and large variations in unemployment. Lastly, the nature of the inference problem determined by the pattern of incomplete information produces serially correlated movements conditioned on large permanent shocks.     

Home production,labor wedges,and international business cycles

Non-separabilities due to home production break the link between market consumption and its marginal utility and help explain several stylized facts of the open economy. In an estimated two-country model with complete asset markets in which home production generates a labor wedge that mimics its empirical counterpart, output is more correlated than consumption across countries, labor inputs and labor wedges are positively correlated across countries, and relative market consumption is negatively related to the real exchange rate. Evidence from time use surveys corroborates some of the predictions of the model.     

Inattentive consumers and international business cycles

This paper presents and studies the properties of a sticky information exchange rate model where consumers and producers update their information sets infrequently. Introducing inattentive consumers has important implications. Through a mechanism resembling the limited participation models, exchange rate volatility observed in the data can be addressed for reasonable values of risk aversion. The model generates more persistence in output, consumption and employment which brings us closer to the data. Impulse responses to monetary shocks are hump shaped, consistent with the empirical evidence. Forecast errors of inattentive consumers provide a channel to reduce the correlation of relative consumption and real exchange rate. The decline in the correlation is quantitatively small for our benchmark model. Model generates a substantial amount of consumer forecast errors when producers are attentive and productivity shocks are persistent. This specification results in a large decline of the correlation of real exchange rate and relative consumption due to consumer inattentiveness. When trade elasticity is set to values at the low end of macro estimates or at higher values consistent with sectoral estimates, the correlation is in the negative territory with inattentive consumers.     

Durable goods,financial frictions,and business cycles in emerging economies

Business cycles in emerging economies display very volatile consumption and strongly countercyclical trade balance. We show that aggregate consumption in these economies is not more volatile than output once durables are accounted for. Then, we present and estimate a real business cycles model for a small open economy that accounts for this empirical observation. Our results show that the role of permanent shocks to aggregate productivity in explaining cyclical fluctuations in emerging economies is considerably lower than previously documented. Moreover, we find that financial frictions are crucial to explain some key business cycle properties of these economies.     

Trade, production sharing, and the international transmission of business cycles

Countries that are more engaged in production sharing exhibit higher bilateral manufacturing output correlations. We use data on trade flows between US multinationals and their affiliates as well as trade between the United States and Mexican maquiladoras to measure production-sharing trade and its link with the business cycle. We then develop a quantitative model of international business cycles that generates a positive link between the extent of vertically integrated production-sharing trade and internationally synchronized business cycles. A key assumption in the model is a relatively low elasticity of substitution between home and foreign inputs in the production of the vertically integrated good.     

Cointegrated TFP processes and international business cycles

A puzzle in international macroeconomics is that real exchange rates are highly volatile. Standard international real business cycle (IRBC) models cannot reproduce this fact. This paper provides evidence that TFP processes for the U.S. and the “rest of the world” are characterized by a vector error correction model (VECM) and that adding cointegrated technology shocks to the standard IRBC model helps to explain the observed high real exchange rate volatility. Also, the model can explain the observed increase in real exchange rate volatility with respect to output in the last 20 years by changes in the parameters of the VECM.     

European business cycles and stock return predictability

This paper finds that the European leading economic indicator, a prime business cycle indicator for the European economies published by the OECD, can strongly predict European stock returns and generate utility gains. Importantly, the predictive power of the European indicator is above and beyond that contained in the country-specific leading indicator. Furthermore, we find that the predictive power of the European indicator is stable.     

Gold rush fever in business cycles

A flexible price model of the business cycle is proposed, in which fluctuations are driven primarily by inefficient movements in investment around a stochastic trend. A boom in the model arises when investors rush to exploit new market opportunities even though the resulting investments simply crowd out the value of previous investments. A metaphor for such profit driven fluctuations are gold rushes, as they are periods of economic boom associated with expenditures aimed at securing claims near new found veins of gold. An attractive feature of the model is its capacity to provide a simple structural interpretation to the properties of a standard consumption and output Vector Autoregression.     

Learning asymmetries in real business cycles

When a boom ends, the downturn is generally sharp and short. When growth resumes, the boom is more gradual. Our explanation rests on learning about productivity. When agents believe productivity is high, they work, invest, and produce more. More production generates higher precision information. When the boom ends, precise estimates of the slowdown prompt decisive reactions: investment and labor fall sharply. When growth resumes, low production yields noisy estimates of recovery. Noise impedes learning, slows recovery, and makes booms more gradual than downturns. A calibrated model generates growth rate asymmetry similar to macroeconomic aggregates. Fluctuations in agents’ forecast precision match observed countercyclical errors of forecasters.“There is, however, another characteristic of what we call the trade cycle that our explanation must cover; namely, the phenomenon of the crisis—the fact that the substitution of a downward for an upward tendency often takes place suddenly and violently, whereas there is, as a rule, no such sharp turning point when an upward is substituted for a downward tendency.” J.M. Keynes (1936)     

Financial markets development,business cycles,and bank risk in South America

In this paper, we examine whether banking crises or business cycles affect the influence of financial markets development on bank risk in a sample of 37 publicly listed commercial banks in seven South American countries over a 22-year period between 1991 and 2012. Banking crises in this region offer a natural setting in which the impact of financial markets development on bank risk is examined. We find that financial markets development improves banks’ capitalization ratio and reduces their exposure to non-traditional banking activities, suggesting that financial markets development on average reduces bank risk. In addition, banking crises and business cycles appear to moderate the impact of financial markets development on bank risk. In the aftermath of banking crises, banks appear to concentrate more on their core traditional banking activities.     

Anticipated growth and business cycles in matching models

In a business cycle model that incorporates a standard matching framework, employment increases in response to news shocks, even though the wealth effect associated with the increase in expected productivity reduces labor force participation. The reason is that the matching friction induces entrepreneurs to increase investment in new projects and vacancies early. If there is underinvestment in new projects in the competitive equilibrium, then the efficiency gains associated with an increase in employment make it possible that consumption, employment, output, as well as the investment in new and existing projects jointly increase long before the actual increase in productivity materializes. If there is no underinvestment, then investment in existing projects decreases, but total investment, consumption, employment, and output still jointly increase.
