Firm-specific capital,inflation persistence and the sources of business cycles

This paper estimates a firm-specific capital DSGE model. Firm-specific capital improves the fit of DSGE models to the data (as shown by a large increase in the value of the log marginal likelihood). This results from a lower implied estimate of the NKPC slope for a given degree of price stickiness. Firm-specific capital leads to a better fit to the volatilities of macro variables and a greater persistence of inflation. It is also shown that firm-specific capital reduces the dependence of New Keynesian models on price markup shocks and that it increases the persistence of output to monetary shocks.     

The New Keynesian business cycle achievements and challenges

The New-Keynesian (NK) business cycle model has presented itself as a potential “workhorse” model for business cycle analysis. This paper seeks to assess afresh the performance of the baseline NK model and its various extensions. The main theme of the paper is that although the dynamic NK literature has secured a robust defence to criticism arising, inter alia, on account of lack of microfoundations, it still has a long way to go in terms of providing a fully satisfactory model of the business cycle. In this regard, it is conjectured that explicitly accounting for the role of heterogeneity in business-cycle dynamics could lead towards a viable solution.

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.

Indeterminacy,capital maintenance expenditures and the business cycle

This paper examines how maintenance expenditures affect the occurrence of indeterminacy in a two-sector model economy, motivated by the empirical fact that equipment and structures are maintained and repaired. McGrattan and Schmitz's (1999) survey on ‘Capital and Repair Expenditures’ in Canada indicates that maintenance expenditures account for a substantial fraction of output and new investment. It is shown that the endogenous maintenance expenditures reduce the requirement of the degree of increasing returns to scale to generate sunspot equilibria. In fact, the minimum level of the returns to scale required could be as low as 1.0179. This aspect is important since empirical works such as Basu and Fernald (1997) suggest that returns to scale is close to constant.     

Ethnic discrimination in hiring,labour market tightness and the business cycle - evidence from field experiments

Several studies using observational data suggest that ethnic discrimination increases in downturns of the economy. We investigate whether ethnic discrimination depends on labour market tightness using data from correspondence studies. We utilize three correspondence studies of the Swedish labour market and two different measures of labour market tightness. These two measures produce qualitatively similar results, and, opposite to the observational studies, suggest that ethnic discrimination in hiring decreases in downturns of the economy.     

Can the facts of UK inflation persistence be explained by nominal rigidity?

It has been widely argued that inflation persistence since WWII has been widespread and durable and that it can only be accounted for by models with a high degree of nominal rigidity. We examine UK post-war data where after confirming previous studies' findings of varying persistence due to changing monetary regimes, we find that models with little nominal rigidity are best equipped to explain it.     

Business cycle and inflation synchronisation in Mainland China and Hong Kong

This paper uses annual data spanning 1962 to 2003 to examine whether business and inflation cycles have become more similar across Chinese provinces as the economy has been liberalised and modernised. We find evidence of synchronisation, although business cycles in a group of mainly northwestern provinces appear to have diverged from those in the rest of China. Both the business and inflation cycles in Hong Kong seem to have become increasingly synchronised with those in the Mainland over recent years.     

Nominal wage contracts, labor adjustment costs and the business cycle

Previous work of monetary dynamic stochastic general equilibrium models with nominal rigidity a la Taylor, particularly the Cho–Cooley model, was abandoned in favor of the New-Keynesian analysis due to the model's failure to deliver business cycle statistics that match the U.S. economy along some key dimensions. In this paper, we take a step in revitalizing the Cho–Cooley avenue of research. We add empirically plausible labor adjustment costs into a model with nominal wage rigidity and find that with labor adjustment costs our model is able to overcome some of the shortcomings otherwise present in the Cho–Cooley framework, specifically high standard deviations of real variables and a countercyclical productivity.     

Labor's share fluctuations, biased technical change, and the business cycle

We extend the basic RBC model to allow for biased technical changes. One broad definition of biased technical changes is changes that directly affect factor elasticities. Given the link between changes in factor elasticities and factor shares, observed fluctuations in US labor's share are motivation for this study. We find that when the technology shock process is calibrated according to US labor's share dynamics, 93 percent of US GDP volatility is accounted for. The observed countercyclical nature of labor's share is accounted for, although the model correlation is too high. As well, the model exhibits business cycles that are qualitatively similar to those of the standard model with neutral technology shocks. These findings, while robust to the short-run properties of various measures of labor's share, are sensitive to the average labor's share used in calibration, e.g., departing from a baseline calibration value of 63 percent, for steady-state labor's shares of 50 percent and 70 percent the model accounts for 107 percent and 84 percent of US GDP volatility respectively.     

Entry and exit of manufacturing plants over the business cycle

This paper analyzes the plant-level entry and exit over the business cycle. We document basic patterns of entry and exit of U.S. manufacturing plants between 1972 and 1997. We find that the entry rate is more cyclical than the exit rate. We also find that the differences in productivity and employment between booms and recessions are particularly larger for entering plants than for exiting plants. Our new finding suggests that the selection at the entry margin may be more important than the selection at the exit margin in understanding the plant-level dynamics over the business cycle.     

Stock prices and inflation hedged firms

As the Federal Reserve continues its near-zero rate policy, the threat of inflation remains a concern among both policymakers and businesses. This article uses over 30 years of accounting data and stock returns to examine how publicly traded firms respond to increasing inflation expectations. We first examine whether firms make balance sheet adjustments in response to expected inflation. We then examine whether these activities have a positive effect on stock prices. We find that firms increase inventory, increase capital expenditures and reduce long-term debt when there is an increased expectation of inflation. We then find that firms that increase inventory in this economic regime are rewarded in the market. Markets also reward firms that increase their cash positions and reduce long-term debt possibly suggesting investor flight to safety.     

Accounting for the business cycle: Nominal rigidities, factor heterogeneity, and Austrian capital theory

An Austrian interpretation of the New Keynesian small menu cost model of the business cycle is proposed. Austrian and New Keynesian business cycle theories share the feature that the cycle is generated by rigidities which prevent the economy from adapting instantaneously to changing conditions. Austrian business cycle theory is capital-based, focusing on credit expansion which artificially lowers interest rates and causes an investment boom and unsustainable business expansion. In contrast, the New Keynesian small menu cost model of the business cycle is based on nominal rigidities which prevent markets from clearing. Small menu costs introduce dichotomous behavior, where firms find it locally optimal to avoid instantaneous output price adjustments in the face of the cost, but this local optimum results in economy-wide output and employment fluctuations which are much greater in relative magnitude. The small menu cost model of the business cycle is extended and reinterpreted in light of Austrian business cycle theory with heterogeneous, multiply-specific capital, thus providing a rigorous formalization of the Austrian business cycle. The Austrian interpretation of this New Keynesian model fortuitously addresses several of its shortcomings. JEL classification B53, E12, E23, E32     

The response of capital goods shipments to demand over the business cycle

We study how producers of capital goods set shipments in response to fluctuations in new orders. We find that shipments respond more to orders when new orders fall below a certain level relative to shipments, usually after orders plunge in recessions. This cyclical change in producers’ behavior accounts for a considerable portion of the downturn in equipment investment in the 2001 and 2008–9 recessions. A simple model of production to order suggests that heightened persistence in new orders growth may explain the greater responsiveness of shipments, as may increases in the producers’ target delivery lag.     

Capacity constraints, asymmetries, and the business cycle

We study how an occasionally binding capacity constraint affects the properties of business cycles. A real business cycle model is constructed where production takes place at individual plants and the number of plants operated varies over the cycle. The capacity constraint binds in states where all plants are operated. We derive the aggregate production function for this economy, which turns out to differ from the standard Cobb–Douglas function while retaining its desirable properties. The business cycle features of this one-sector growth model are similar to those of a standard real business cycle model in most respects. Our model does, however, display some properties of actual economies that standard models do not. In particular, business cycles in our model are asymmetric—troughs are deeper on average than peaks are tall. Also, labor's share of income is counter-cyclical, as it is in US data.     

The changing role of house price dynamics over the business cycle

In this paper, we attempt to analyse the relationship between house price dynamics and the business cycle. Employing a time-varying transition probability Markov switching framework, we provide empirical evidence that house price growth may prove a useful leading indicator for turning point detection. Focusing on three countries, the US, UK and Spain, we furthermore provide evidence that although potentially informative from an overall perspective in business cycle modelling, the significance of signals contained in house prices may not be symmetric across the identified high growth and low growth states. In addition, we suggest a possible range of values for house price deflation which may trigger a recession the following period.     

Labor market institutions and aggregate fluctuations in a search and matching model

This paper explores the influence of labor market institutions on aggregate fluctuations. It uses a dynamic, stochastic, general equilibrium model characterized by search and matching frictions in the labor market and nominal rigidities in the goods market. It finds that firing costs and unemployment benefits can have substantial effects on aggregate fluctuations. Increasing firing costs decreases the volatility of output, employment, and job flows due to the reduction in the mass of jobs sensitive to disturbances and lower incentives for firms to hire and fire workers. Hence, firms adjust to shocks mainly through prices, causing inflation to become more volatile. Raising unemployment benefits has the reverse effect on aggregate fluctuations.     

Technology,employment and the business cycle in post-transition countries of the EU

This article analyses the importance of technology and non-technology shocks in the business cycles of European Union post-transition countries. Different assumptions of New Keynesian and Real Business Cycle theory are tested. The results demonstrate that a non-technology shock is more important in explaining business cycles in post-transition countries, although a technology shock is not trivial. The technology shock cannot replicate basic business cycle facts observed in the data: it produces a low or negative correlation between employment and GDP, and a strong negative correlation between labour productivity and employment. Technology and non-technology GDP components are analysed in the transition and post-transition period. The results show a non-technology shock was the dominant source of business cycles both during and after the transition period.     

Fiscal policy,government size and EMU business cycle synchronization

We provide new evidence on the effects of fiscal policy and government size on pairwise business cycle synchronization in EMU. A novel time-varying framework is employed to estimate business cycle synchronization and subsequently a panel approach is used to establish the role of fiscal variables in determining the pairwise synchronization observations across time. The findings suggest similarities in the size of the public sector, yet divergence in fiscal policy stance, matter for the determination of business cycle synchronization. Hence, increased fiscal federalism in EMU will contribute to increased business cycle synchronization. Our results remain robust to different specifications and sub-periods.     

Gender and central banking

Female Central Bank chairs represent but a tiny minority. To understand why, this article analyzes socio-economic and socio-political characteristics of the countries where women have chaired Central Banks. Then, it suggests that gender differences in preferences as regards monetary policy goals may have some influence. This hypothesis is based on an empirical analysis showing that female Central Bank chairs focus more than their male counterparts on achieving the price stability goal. This means, then, that women are more resistant than men to political pressures. Finally, it concludes that gender differences in degree of conservatism may be an explanatory factor in female underrepresentation in the Central Bank chairs.
