Is time-varying firm-level uncertainty a major cause or amplifier of the business cycle? This paper investigates this question in the context of a heterogeneous-firm RBC model with persistent firm-level productivity shocks and lumpy capital adjustment, where cyclical changes in uncertainty...

Using a German firm-level data set, this paper is the first to jointly study the cyclical properties of the cross-sections of firm-level real value added and Solow residual innovations, as well as capital and employment adjustment. We find two new business cycle facts: 1) The cross-sectional...

Concave hiring rules imply that firms respond more to bad shocks than to good shocks. They provide a unified explanation for several seemingly unrelated facts about employment growth in macro and micro data. In particular, they generate countercyclical movement in both aggregate conditional...

Using a two-sector estimated DSGE model with a financial channel we show the sector where TFP news arrives matters for its propagation and quantitative importance. Anticipated increases in TFP expected to arrive in the consumption sector are expansionary while those in the investment sector are...

In many countries, the legal system or social norms ensure that firms are stakeholder oriented. We analyze the advantages and disadvantages of stakeholder-oriented firms that are concerned with employees and suppliers compared to shareholder-oriented firms in a model of imperfect competition....

With public services such as health and education, it is not straightforward for consumers to assess the quality of provision. Many such services are provided by monopoly not-for-profit providers and there is concern that for-profit providers may increase profit at the expense of quality. This...

There is substantial consensus in the literature that positive uncertainty shocks predict a slowdown of economic activity. However, using U.S. data since 1950 we show that the macroeconomic response pattern to stock market volatility shocks has changed substantially over time. The negative...

This paper shows that dynamic inefficiency can occur in dynamic general equilibrium models with fully optimizing, infinitely-lived households even in a situation with underinvestment. We identify necessary conditions for such a possibility and illustrate it in a standard R&D-based growth model....

This paper estimates the effects of tax changes on the U.K. economy. Identification is achieved by isolating the ‘exogenous' tax policy shocks in the post-war U.K. economy using a narrative strategy as in Romer and Romer (2010). The resulting tax changes are shown to be unforecastable on the...

The Friedman rule states that steady-state welfare is maximized when there is deflation at the real rate of interest. Recent work by Khan et al (2003) uses a richer model but still finds deflation optimal. In an otherwise standard new Keynesian model we show that, if households have hyperbolic...
