WHY SOCIAL PREFERENCES MATTER – THE IMPACT OF NON-SELFISH MOTIVES ON COMPETITION, COOPERATION AND INCENTIVES

A substantial number of people exhibit social preferences, which means they are not solely motivated by material self-interest but also care positively or negatively for the material payoffs of relevant reference agents. We show empirically that economists fail to understand fundamental economic questions when they disregard social preferences, in particular, that without taking social preferences into account, it is not possible to understand adequately (i) effects of competition on market outcomes, (ii) laws governing cooperation and collective action, (iii) effects and the determinants of material incentives, (iv) which contracts and property rights arrangements are optimal, and (v) important forces shaping social norms and market failures.     

Board Overlap, Seat Accumulation and Share Prices

We examine the board overlap among firms listed in Switzerland. Collusion, managerial entrenchment, and financial participation cannot explain it. The overlap appears to be induced by banks and by the accumulation of seats by the most popular directors. We also document that seat accumulation is negatively related to firm value, possibly because of the conflicts of interest that multiple directorships induce and the time constraints directors face. Contrary to popular beliefs, however, the directors of traded firms do not generally hold more than one mandate in other traded firms. They do hold multiple seats in non-traded firms.     

The impact of monetary policy on stock market bubbles and trading behavior: Evidence from the lab

We investigate the effect of monetary policy on stock market bubbles and trading behavior in experimental asset markets. We introduce the possibility of investing in interest bearing bonds to the widely used laboratory asset market design of Smith et al. (1988). Treatment groups face a variable interest rate policy which depends on asset prices, while control groups are subjected to a constant interest rate. We observe a strong impact of our interest rate policy on liquidity in the stock market but only a small impact on bubbles. However, we find that announcing the possibility of reserve requirements significantly reduces bubbles.     

Impacts of Climate Change on Winter Tourism in the Swiss Alps

This paper examines the impacts of three consecutive snow-deficient winters at the end of the 1980s on the winter tourism industry in Switzerland. It is shown that ski areas in lower areas suffered severe consequences. Ski areas at higher altitudes (in particular glacier ski resorts) on the other hand increased their transport figures and therefore profited from the lack of snow in lower areas. The snow-reliability of all Swiss ski fields under current climate conditions and under a 2"C warming are investigated. Under current climate conditions 85% of all Swiss ski areas are snow-reliable. This number would drop to 63% if temperatures were to rise by 2"C. This is likely to threaten the regionally balanced economic growth which winter tourism has provided. Possible strategies for the winter tourism industry to adopt if climate change occurs are presented.     

Fiscal decentralization under free mobility

In this paper it is shown that, under the proper convexity assumption, any efficient allocation of an economy subdivided into locationally separated regions can be sustained by means of fiscal decentralization with profit maximizing local governments. For that to be true, however, a system of intergovernmental grants is needed. Without such grants, fiscal decentralization and Tiebout equilibria are closely related concepts. Since a Tiebout equilibrium generally fails to exist [Bewley (1981)], these grants play an important role not only for redistribution but, in the first place, to make fiscal decentralization a feasible allocation mechanism.     

Protecting Minority Shareholders: Listed versus Unlisted Firms

Listed firms have an incentive to render themselves attractive to investors at large. This paper examines whether listed and unlisted firms differ in their care for minority shareholders and finds supporting evidence. We examine control structure, disclosure, board architecture and processes, and director compensation. The corporate governance package in listed firms differs from that in unlisted firms in terms of levels and mix of the different provisions. The data also suggest that listed firms perform better.     

Fairness, errors and the power of competition

In this paper, we investigate the effects of competition on bargained outcomes. We show that the neglect of either fairness concerns or decision errors will prevent a satisfactory understanding of how competition affects bargaining. We conducted experiments which demonstrate that introducing a small amount of competition to a bilateral ultimatum game – by adding just one competitor – induces large behavioral changes among responders and proposers, causing large changes in accepted offers. Models that assume that all people are self-interested and fully rational do not adequately explain these changes. We show that a model which combines heterogeneous fairness concerns with decision errors correctly predicts the comparative static effects of changes in competition. Moreover, the combined model is remarkably good at predicting the entire distribution of offers in many different competitive situations.
