Abstract There is ample evidence that the frequency of price adjustments differs substantially across sectors. This paper introduces sectoral heterogeneity in price stickiness into an otherwise standard sticky price model to study how it affects the dynamics of monetary economies. Qualitative...

Abstract In this paper, we empirically examine the portfolio-rebalancing effects stemming from the policy of “quantitative monetary easing” recently undertaken by the Bank of Japan when the nominal short-term interest rate was virtually at zero. Portfolio-rebalancing effects resulting from...

Abstract In the recent macro literature the effect of competition has been analyzed by comparing economies with the same market structure but different degrees of substitutability. In this note, we argue that this approach may mingle the price effect of competition with a pure allocation effect....

Abstract Jovanovic and Ueda (1997) consider a principal-agent model with moral hazard and renegotiation. A noisy signal of the agent's output is observed before renegotiation takes place and actual output is revealed after renegotiation. If the agent is restricted to choose pure strategies it...

Abstract The paper argues that a Cobb-Douglas specification may be a reasonable description of the Finnish aggregate production function when a sufficiently long time period (the 20th century) is considered. It is, however, a misleading description of the production technology for the post-WWII...

Abstract In this paper we revisit the work of Jones (1995a) which provided strong evidence against the empirical validity of AK-type models that predict increasing output growth rates as a result of permanent movements in the physical investment rate. For that purpose, we employ recently...

Abstract We relate the negative correlation between income and the ratio of high to low-tech human capital and the positive correlation between income and investment on R&D, both present in developed countries, to the transition to a services economy. To this end a growth model with endogenous...

Abstract Although a lot has been written on the link between debt maturity and financial crises, it remains puzzling why the private sector in emerging market economies holds such a large share of short-term debt in the presence of substantial macroeconomic risk. To understand this phenomenon,...

Abstract This paper introduces a signalling model of conspicuous consumption in the context of an endogenous growth model. Agents purchase luxury goods to signal their social status. 'Invidious Comparison' takes place when rich agents successfully identify themselves, whereas 'Pecuniary...

Abstract This paper presents a new approach to assess the role of price mismeasurement in the productivity slowdown. I invert the firm’s investment decision to identify the embodied and disembodied components of productivity growth. With a Cobb-Douglas production function, output price...
