Infrastructure provision and international market share rivalry

The paper examines a model of strategic infrastructure investment. Two oligopolistic firms compete on home and foreign product markets for market shares. The national governments support the firms in the market rivalry by providing cost reducing public infrastructure services that are financed out of taxing an input used in the production process. It is shown, that infrastructure policy can be used as an instrument for strategic trade policy. However, governments are facing the problem of balancing the burden of taxation and the benefits of infrastructures. The theoretical model also raises some critical issues with respect to the policy relevance of recent empirical infrastructure research.     

Price competition and market transparency: evidence from a random response technique

Surveys can increase market transparency when information asymmetries are present—but this will only happen when respondents answer questions truthfully. Sometimes, however, it might not be in the respondents’ best interest to provide truthful information on their firm or market. This will be especially true when other firms can exploit any information they provide. Understanding when, and under what conditions, respondents answer questions truthfully is important to researchers studying these markets and to policymakers using firm surveys to identify ways of improving the business environment. Using data from two countries in South Asia, this paper uses a random response technique to identify respondents that do not answer truthfully. We label these respondents as ‘reticent’. We show that respondents become more reticent when their firms face intense price competition. We argue that this is because intense competition gives respondents a greater incentive to misreport information to reduce market transparency.     

Consumer Ownership in Liberalized Electricity Markets. The Case of Denmark

The continuation of consumer ownership has been an important part of the Danish electricity reform from 1999. Consumer ownership refers to either a consumer co-operative or a municipal utility. Contrary to conventional wisdom, consumer ownership can be supported by solid arguments from modern economic theory of organization. These arguments are presented and confronted with both present and future situation in Denmark. The development of the electricity supply industry after the Second World War has emptied consumer ownership of much of its original content. Nowadays, most consumers consider their electric utility as the (monopoly) supplier of a good they demand and not as something they own. Therefore, obligatory consumer ownership as specified in the new Danish Electricity Act of 1999 cannot be relied on to guarantee security of supply and reasonable prices for small consumers     

Relative concerns of rural-to-urban migrants in China

As their environment changes, migrants constitute an interesting group to study the effect of relative income on subjective well-being. This paper focuses on the huge population of rural-to-urban migrants in China. Using a novel dataset, we find that the well-being of migrants depends on several reference groups: it is negatively affected by the income of other migrants and workers of home regions; in contrast, we identify a positive, ‘signal’ effect vis-à-vis urban workers: larger urban incomes indicate higher income prospects for the migrants. These effects are particularly strong for migrants who wish to settle permanently, decline with years since migrations and change with other characteristics including work conditions and community ties.     

The short and long-run interdependencies between the Eurozone and the USA

We estimate quarterly cointegrating vector autoregressive models for the Eurozone and the USA based on long-run restrictions derived from a dynamic open economy model. Three long-run relations between the Eurozone and the USA emerge: relative purchasing power parity, international interest parity and a stationary output gap between the two economies. Generalized impulse response functions show differences in the dynamic adjustment of the two economies. Due to the I(1)-characteristic of both output series and the stability conditions imposed by the long-run equilibrium relationships, shocks to the model produce level effects only, while growth rates converge to their long-run averages.

Increasing life expectancy and optimal retirement in general equilibrium

We analytically assess the effects of changes in longevity on the interest rate, the consumption-savings behavior, and the optimal retirement decision within a dynamic general equilibrium setting. We derive a simple sufficient condition for which the optimal retirement age always increases with life expectancy. Numerical assessment reveals that for realistic parameter values that reflect the situation in industrialized countries, the optimal retirement age indeed increases with life expectancy and the sufficient condition tends to be fulfilled. Together with the fact that the actual retirement age did not increase in industrialized countries over the last decades, while there have been large improvements in longevity, this leads us to conclude that strong monetary and institutional incentives for early retirement exist and these counteract the effects of increasing life expectancy. Our policy conclusion is that the retirement age should be partially linked to life expectancy and that incentives for early retirement should be removed.     

Low price signals high capacity

We study pricing in a model where buyers are homogeneous and sellers have either capacity one or two. We show that if buyers observe prices but not capacities then an equilibrium exists where sellers of capacity two post lower prices than sellers of capacity one. The equilibrium satisfies the intuitive criterion.     

Corrigendum to “Stable matchings and preferences of couples” [J. Econ. Theory 121 (1) (2005) 75–106]

We correct an omission in the definition of the domain of weakly responsive preferences introduced in [B. Klaus, F. Klijn, Stable matchings and preferences of couples, J. Econ. Theory 121 (2005) 75–106] or KK05 for short. The proof of the existence of stable matchings [KK05, Theorem 3.3] and a maximal domain result [KK05, Theorem 3.5] are adjusted accordingly.     

Spatial growth and industry age

Between 1970 and 2000 employment growth across U.S. counties exhibited very different patterns in manufacturing and services. Whereas manufacturing employment growth was negatively related to initial manufacturing employment across the entire distribution of counties, service employment growth was positively related to initial service employment for intermediate sized counties. This paper presents a theory to rationalize these facts. Local sectoral growth is driven by technological diffusion across space and depends on the age of the sector. The theory correctly predicts the relation between county employment growth and initial county employment in manufacturing at the turn of the 20th century.
