MARKET PERFORMANCE WITH MULTIPRODUCT FIRMS*

We revisit the fundamental issue of market provision of variety associated with Chamberlin, Spence, and Dixit‐Stiglitz when firms sell multiple products. Both products and firms are (horizontally) differentiated. We propose a general nested demand framework where consumers first decide upon a firm then which variant to buy and how much (the nested CES is a special case). We use it to determine the market's biases when firms compete in product ranges and prices. The market system attracts too many firms with too few products per firm: firms restrain product ranges to relax price competition, but this exacerbates over‐entry.     

Spending,saving, or investing? Risk management in sixteenth‐century Dutch households1

In the past one of the main challenges to households was that of coping with adversity. War, plague, famine, and flood were a constant threat, and could reduce what little improvements families had made in productivity. Economic growth therefore required a means of absorbing external adversities. To see how well late medieval households coped with adversity, this investigation focuses on the households of a small town and its surroundings in early modern Holland. Our findings reveal that several severe external shocks around 1500 had little effect on the general level or distribution of wealth, which suggests that certain forms of insurance may have protected the population. The results show that households increasingly invested in capital markets rather than employing such techniques as scattered holdings and hoarding. This fact indicates that such investment played a vital role in a household's risk aversion strategy. The change from unproductive to more productive risk‐aversion strategies also provides some clues about progress with respect to insurance during Holland's financial revolution.     

Private,Social, and Self‐Insurance for Long‐Term Care in the Presence of Family Help

We study the political determination of the level of social long‐term care insurance when voters can top up with private insurance, saving and family help. Agents differ in income, probability of becoming dependent and of receiving family help, and amount of family help received. Social insurance redistributes across income and risk levels, while private insurance is actuarially fair. The income‐to‐dependency probability ratio of agents determines whether they prefer social or private insurance. Family support crowds out the demand for both social and, especially, private insurance, as strong prospects of family help drive the demand for private insurance to zero. The availability of private insurance decreases the demand for social insurance but need not decrease its majority‐chosen level. A majority of voters would oppose banning private insurance.     

A Conference on Postcrisis Banking

This article provides an introduction to the special issue. We focus on four themes that are important for policymakers and researchers alike in view of the experiences of the global financial crisis of 2007–09 and the ensuing sovereign debt crisis in the euro area: the relevance of the banking sector for the real economy, the future structure and regulation of the banking sector, the efficacy of past and current regulatory reforms, and the impact of cross‐border banking on economic stability and financial development.     

El sindicalismo israelí ante el empleo atípico. El fenómeno de la liminalidad permanente

Los comités de empresa israelíes se están adaptando a la economía neoliberal y a las transformaciones laborales concomitantes con una doble postura: por un lado tratan de hacer frente a esta reformulación del capitalismo para salvaguardar los derechos de los trabajadores, y por otro aceptan cada vez más las formas atípicas de empleo. Esta contradicción los sitúa en un estadio de «liminalidad» permanente, en el que sus funciones se reducen a una mera búsqueda de compromisos y soluciones ad hoc. Como consecuencia, su lucha contra los efectos adversos del empleo atípico sigue siendo puntual y fragmentada, lo que contribuye a consolidar estas modalidades de empleo.     

What Makes the Output–Inflation Trade‐Off Change? The Absence of Accelerating Deflation in Japan

It is standard to model the output–inflation trade-off as a linear relationship with a time-invariant slope. We assess empirical evidence for two sets of theories that allow for endogenous variation in the slope of the short-run Phillips curve. At an empirical level, we examine why large negative output gaps in Japan in the late 1990s did not lead to accelerating deflation but instead coincided with stable, albeit moderately negative inflation. Our results suggest that this episode is most convincingly interpreted as reflecting a gradual flattening of the Phillips curve. We find that this flattening is best explained by models with endogenous price durations. These models imply that in any economy where trend inflation is substantially lower (or substantially higher) today than in past decades, time variation in the slope of the Phillips curve has become too important to ignore.
