Agency costs and business cycles

Summary. This paper develops a model with endogenous agency costs that is otherwise quite similar to the canonical real business cycle model. The traditional assumption in the literature is that these agency costs arise in the production of investment goods. In contrast, this paper assumes that these costs are all encompassing in the sense that they arise in the production of aggregate output. The paper explores both the importance of the investment vs. output assumption for business cycle dynamics, and the conditions under which these agency models can deliver amplification and/or persistence. The paper has two principal conclusions. First, in terms of amplification and propagation, the output model performs worse than does the investment model. This arises because a variable distortion in the investment market has more of an impact than a comparable distortion in the output market. Second, in this model with optimal consumption choice by entrepreneurs, there is a clear tension between amplification and persistence.

Multi-dimensional risk and the cost of business cycles

This paper analyzes the welfare costs of business cycles when workers face uninsurable idiosyncratic labor income risk. In accordance with the previous literature, this paper decomposes labor income risk into an aggregate and an idiosyncratic component, but in contrast to the previous literature, this paper allows for multiple sources of idiosyncratic labor income risk. Using the multi-dimensional approach to idiosyncratic risk, this paper provides a general characterization of the welfare cost of business cycles when preferences and the (marginal) process of individual labor income in the economy with business cycles are given. The general analysis shows that the introduction of multiple sources of idiosyncratic risk never decreases the cost of business cycles, and strictly increases it if there are cyclical fluctuations across the different sources of risk. This paper also provides a quantitative analysis based on a version of the model that is calibrated to match US labor market data. The quantitative analysis suggests that realistic variations across two particular dimensions of idiosyncratic labor income risk increase the welfare cost of business cycles by a substantial amount.     

Economic growth,business cycles and products variety: exploring the role of demand satiety

The paper presents a model of economic growth based on a population of heterogeneous and interacting agents. This model succeeds to generate - in a single framework - GDP growth and cycles as well as product life cycles. Contrary to the existing literature, we find that an increasing variety of consumer goods is not a necessary condition for sustaining the economic growth when consumers are subject to satiation. Indeed, intensive creative-destruction - that is an intensive process of sectors births and deaths - appears to be a more powerful growth engine. We also find that changing consumers’ satiety thresholds is likely to affect the nature of the correlation between the cyclical components of macroeconomic time series.     

Countercyclical markups and news-driven business cycles

The standard one-sector real business cycle model is unable to generate expectations-driven fluctuations. The addition of countercyclical markups and modest investment adjustment costs offers an easy fix to this conundrum. The simulated model replicates the regular features of U.S. aggregate fluctuations.     

Global banking and international business cycles

This paper incorporates a global bank into a two-country business cycle model. The bank collects deposits from households and makes loans to entrepreneurs, in both countries. It has to finance a fraction of loans using equity. We investigate how such a bank capital requirement affects the international transmission of productivity and loan default shocks. Three findings emerge. First, the bank's capital requirement has little effect on the international transmission of productivity shocks. Second, the contribution of loan default shocks to business cycle fluctuations is negligible under normal economic conditions. Third, an exceptionally large loan loss originating in one country induces a sizeable and simultaneous decline in economic activity in both countries. This is particularly noteworthy, as the 2007–09 global financial crisis was characterized by large credit losses in the US and a simultaneous sharp output reduction in the US and the Euro Area. Our results thus suggest that global banks may have played an important role in the international transmission of the crisis.     

Nonlinear dynamism of innovation and business cycles

The aim of this paper is to describe the nonlinear dynamism of innovation and to clarify the role of innovation for economic development in terms of Kondratiev business cycles, especially the causal relation of the bubble economy and depressions with innovations. Any paradigm of technological innovation develops within a definite time span reaching maturity. This nonlinear nature clarifies many characteristic features of innovation. Schumpeters innovation theory on business cycles is examined through this dynamism. Trunk innovation is defined as that which plays a decisive role in building infrastructures and inducing subsequent innovations. Every innovation has its own technological development period just before the innovation diffusion. The emergence of new markets can be estimated by chasing the ongoing technologies.JEL Classification: E32, L16, O11, O14, O30Paper presented at the 9th Conference of the International J.A.

Optimal research and development and the cost of business cycles

While research and development (R&D) investment has been procyclical in the post-war period, recent literature suggests that the optimal path for R&D is countercyclical, and that the economy would be better off by subsidizing R&D in recessions. The objective of this paper is to analyze the welfare effects of distortions in the intertemporal allocation of R&D resources and to compare diverse policy interventions so as to improve social welfare. To this end, we introduce a calibrated dynamic stochastic general equilibrium model with Schumpeterian endogenous growth that is capable of explaining the observed procyclicality of R&D. Our results show that the cost of business cycles is lower in the decentralized economy with procyclical R&D than in the efficient allocation with countercyclical R&D. This is because the suboptimal propagation of shocks in the decentralized equilibrium offsets some of the existing steady-state distortions. In this second-best context, countercyclical R&D subsidies have no positive effect on welfare. In contrast, fiscal policies aimed at restoring the optimal steady-state produce large welfare gains.     

Discoveries, innovations, and business cycles

There is considerable evidence that the density of basic innovations is peaked at definite periods with intervals of about 40–60 years. This has been used as support for the behavior of economic cycles as postulated by Kontradieff and amplified by Schumpeter. Recently some economists have used this model to forecast economic recovery in the middle or late 1980s.This paper points out that the shape of the clusters of innovation or inventions are different and sharper than those of economic depression or economic recovery. The transfer of knowledge from basic inventions to industrial innovations shortens as one moves from the 18th to the 20th century, and some probable explanations for this are offered. The importance of discoveries and limited discoveries to the process of invention and innovation is discussed. Also shown is that discoveries reveal cluster phenomena which are functionally related to the clusters of invention and innovation.     

Fractional integration and business cycle features

We show in this article that fractionally integrated univariate models for GDP lead to a better replication of the main business cycle characteristics. We firstly show that the business cycle features are clearly affected by the degree of integration as well as by the other short run (AR, MA, etc.) components of the series. Then, we model the real GDP in the UK and the US by means of fractionally ARIMA (ARFIMA) model, and show that the time series can be specified in terms of this type of model with orders of integration higher than one but smaller than two. Comparing the ARFIMA specifications with those based on ARIMA models, we show via simulations that the former better describe the business cycles features of the data.Jel classification: C12, C15, C22The authors want to thank two anonymous referees for wise remarks.

An Austrian view of expectations and business cycles

Austrian economists have contributed several important concepts to business cycle theory including: inter-temporal coordination of production and consumption, heterogeneous specificity of capital, non-neutrality of money, and the capital structure of production. Noticeably lacking, however, is a clear theory of expectations. Recent Austrian responses to rational expectations critiques—such as positing a prisoner’s dilemma, heterogeneous entrepreneurs, and adverse selection—try to fill this gap. But much work remains to be done developing an Austrian theory of expectations, one where they are endogenous to the market process and market institutions. This paper explores how people adapt their expectations to changing market phenomena based upon their perceived costs and benefits of doing so. It then applies endogenous expectations to the 2008 financial crisis.     

International business cycles and the relative price of investment goods

Abstract Is the relative price of investment goods a good proxy for investment specific technology? We model this relative price in a flexible price international economy with two fundamental shocks, namely, the total factor productivity (TFP) shock and the investment‐specific technology (IST) shock. We show that the one‐to‐one correspondence between the IST shock and the relative price of investment goods breaks down in an international economy because of the short‐run correlation between the terms of trade and the relative price of investment goods. The data congruent negative correlation between the investment rate and the relative price of investment goods thus does not necessarily reflect decline in investment frictions (rise in IST), as suggested by many studies. A calibration experiment with the US data demonstrates that such an inverse relation between rate of investment and the relative price of investment goods basically reflects the positive effect of TFP on the terms of trade for a broad range of economies where the home bias in consumption exceeds investment and there is a sizable adjustment cost of investment.     

Dynamic employment adjustments over business cycles

This paper uses U.S. monthly industrial production employment data between 1964 and 2000 to examine the dynamic labor adjustments of production workers and nonproduction workers in both the short and long-run. The results from the short-run analysis show that the dynamic adjustment of production workers is consistent with business cycles. However, the adjustment of nonproduction workers is relatively fixed, lags behind the shocks over business cycle changes, and exhibits the quasi-fixed factor property. In the long-run, we found that nonproduction workers and production workers are cointegrated indicating that the two series are in long-run equilibrium.First version received: March 2002/Final version received: November 2003We would like to thank James McClure, participants in the Economics Department seminar series at Ball State University, and an anonymous referee for their comments and suggestions.     

Asset prices and business cycles under market incompleteness

In this paper, we study the quantitative implications of a real business cycle model where the firm is the capital owner, households are heterogeneous, and markets are incomplete due to restricted asset trade. Since, under these assumptions, the usual firm objective is no longer well defined, several non-standard objectives are incorporated into the model. These include variants of market value maximization and a utility function for the firm. We find that the presence of market incompleteness alters little the behavior of asset returns. On the other hand, the behavior of the macroeconomic aggregates is quite sensitive to the firm objective, which affects the capital accumulation path. In contrast to conventional findings, capital is not necessarily higher when markets are incomplete. In addition, the different capital accumulation effects imply that shareholders with different asset wealth might prefer different firm objectives.     

Endogenous business cycles and systematic stabilization policy*

We study the effects of fiscal policy rules on the determinacy of rational expectations equilibrium in a perfectly competitive monetary model with constant returns. Government spending implies a distortion of the monetary steady state due to the implied taxation. We show that policy rules that let the GNP share of government spending depend sufficiently negatively on increases in GNP stabilize the economy with respect to endogenous fluctuations for arbitrarily little distortion of the steady state at which stabilization occurs. The rules do not involve lump‐sum taxation, negative income taxation, or exact knowledge of the economy's laissez‐faire steady state.     

Consumption,wealth and business cycles in Germany

This paper studies the long-run relationship between consumption, asset wealth and income—the consumption–wealth ratio—based on German data from 1980 to 2003. We find that departures from this long-run relationship mainly predict adjustments in income. The German consumption–wealth ratio also contains considerable forecasting power for a range of business cycle indicators, including the unemployment rate. This finding is in contrast to earlier studies for some of the Anglo-Saxon economies that have shown that the consumption–wealth ratio reverts to its long-run mean mainly through subsequent adjustments in asset prices. While the German consumption wealth ratio contains little information about future changes in German asset prices, we report that the U.S. consumption–wealth ratio has considerable forecasting power for the German stock market. One explanation of these findings is that in Germany—due to structural differences in the financial and pension systems—the share of publicly traded equity in aggregate household wealth is much smaller than in the Anglo-Saxon countries. We discuss the implications of our results for the measurement of a potential wealth effect on consumption.

Managing TFT-LCDs under uncertainty: When crystal cycles meet business cycles

Understanding the correlation between the crystal cycle and the business cycle is important, because it can help managers to anticipate change, reduce environmental uncertainty, and formulate operational objectives. To this end, we focused on China and the U.S. in our analysis. We found that the economic indicators that were the most relevant in the characterization of China's huge and burgeoning TFT-LCD market are gross domestic production and industrial production. We complemented this finding by conducting similar analyses in the U.S. market using a more comprehensive list of economic indicators.     

On the endogeneity of an exogenous OCA-criterion: specialisation and the correlation of regional business cycles in Europe

This paper examines whether changes in the degree of correlation of employment cycles across regions (of Belgium, France, Germany, Ireland, the Netherlands, and Spain) can be explained by changing patterns of specialisation. The empirical method adopted carries out pooled regressions for all possible region-pairs which relate moving correlations between the residuals of HP-filtered regional employment to their own past and an index of specialisation. As a test of robustness, the benchmark estimations which originally include dummies for common borders, German unification and relative differences between regional incomes are systematically tested down. The empirical results again highlight the problem of a common monetary policy for uncommon regions within the euro zone.

Expectation driven business cycles with limited enforcement

We explore shocks to expected future productivity in a model with limited enforcement of financial contracts. A microfounded collateral constraint implies that good news about future productivity yield an increase in stock prices, available credit and a general economic expansion.     

Common factors in Latin America's business cycles

We develop a common factor approach to reconstruct new business cycle indices for Argentina, Brazil, Chile, and Mexico (“LAC-4”) from a new dataset spanning 135 years. We establish the robustness of our indices through extensive testing and use them to explore business cycle properties in LAC-4 across outward- and inward-looking policy regimes. We find that output persistence in LAC-4 has been consistently high across regimes, whereas volatility has been markedly time-varying but without displaying a clear-cut relationship with openness. We also find a sizeable common regional factor driven by output and interest rates in advanced countries, including during inward-looking regimes.
