A Model of Reputation in Cheap Talk*

We study a dynamic game of advice where the sender's preferences are unknown to the receiver. The novel feature of the model is that there is more than one type of biased sender. We show that the more equal the proportions of different biases in the sender population, the greater the credibility of the information transmitted. Somewhat surprisingly, however, we also find that the receiver does not benefit from this equality. We discuss our results in the context of political lobbying and show that institutions that increase transparency lower lobbyists' incentives for truthtelling, but unambiguously promote the policymaker's welfare.     

Understanding European unemployment with matching and search-island models

To understand European and American unemployment during the last 60 years, we use a search-island model and four matching models with workers who have heterogeneous skills and entitlements to government benefits. When there is higher turbulence, in the sense of worse skill transition probabilities for workers who suffer involuntary layoffs, high government mandated unemployment insurance (UI) and employment protection (EP) in Europe increase unemployment rates and durations. But when there is lower turbulence, high European EP suppresses unemployment rates despite high European UI. Four matching models differ in how they assign unemployed workers to matching functions. That affects how strongly unemployment responds to increases in turbulence. Heterogeneity among unemployed workers highlights the central role of adverse labor market externalities in matching models and reveals that the cost of posting vacancies is the lynchpin of a matching model.

Controllability and the theory of economic policy: A critical view

It is argued in this paper that the concept of controllability in spite of its intuitive appeal is of limited interest for the theory of economic policy. Controllability implies that a given target can be attained even if the number of instruments is less than the number of independent targets. But there is no guarantee that the economy will be able to stay there. Tirbergen's rule is concerned with the existence of a static equilibrium solution. The controllability concept is concerned with the existence of a dynamic path towards it. But it does not imply that controllability is a dynamic generalization of Tinbergen's rule.     

Monetization and the behavior of velocity in Sweden, 1871–1913

The income velocity of money declined sharply in Sweden between the 1870's and the outbreak of World War I. This decline is explained by a monetization process. An account of this process is given focusing on (a) the growth of commercial banking, (b) changes in wage contracts and in labor markets, and (c) changes in exchange arrangements in the markets for goods. A number of proxy measures of the spreading use of money are presented and included in regressions on velocity. The influence of the monetization variables is compared to the effects of the standard explanatory variables in money demand studies, that is, of real income and interest rates. The econometric results support the view that monetization variables significantly contributed to the fall in velocity. These results question the luxury-good hypothesis of money, suggesting that the standard approach of including real income as an explanatory variable in money demand studies covering long spans of time runs the risk of ignoring important determinants of the secular behavior of velocity.     

Optimal subsidies to declining industries: Efficiency and equity considerations

This paper considers equity versus efficiency in a small economy that subsidizes an industry facing falling world market prices. Subsidies keep up output in the short run when wages and factors are rigid. But once introduced, subsidies become permanent, because of pressures from vested interests. This creates missalocation of resources in the long run. An optimal efficiency subsidy balances the short-run gains and long-run losses. It should be raised when prices fall if there is full employment initially and lowered if there is unemployment. An optimal distribution subsidy, which aims at maintaining the existing income distribution, should always be raised.     

Management problems in welfare services: the role of the “social entrepreneur” in home-help for the elderly, the Valby case

This article deals with the management problems of the traditional welfare state. The article is based on observations and interviews with employees in the home-help service for the elderly in Valby, a suburb of Copenhagen. On the basis of observations and interviews, and with reference to various relevant studies, the history of home-help in Denmark is examined as a “narrative” in order to uncover critical problems and incidents. In Valby an attempt has been made to promote flexibility and interaction with clients, rather than a standardisation of the services offered. The practical expression of this approach can be seen in the shape of a new entrepreneurial role in management, what I call the social entrepreneur. I discuss briefly how support for this new role can be institutionalised. At the theoretical level, I analyse the Valby case using the theory of flexible specialisation. However, the Valby case illustrates the contextual limitations of this theory and the need to complement the approach with an understanding of management problems at the practical level.     

Finance-specific factors as drivers of cross-border investment—An empirical investigation

In this paper we empirically test the role of firm-specific financial characteristics as drivers of international investment and production. We hypothesize that financial strength generates advantages that can be exploited through cross-border investment activity. The hypothesis is tested in a series of binary-response models, using a sample of 1379 European non-financial firms’ international acquisitions. Controlling for traditional firm- and target-country-specific foreign direct investment (FDI) determinants, we find strong evidence that financial factors play a significant role in explaining cross-border investment. We conclude that without explicit consideration of the financial dimension, firms’ FDI decisions cannot be properly understood.
