Quality and Welfare in a Mixed Duopoly with Regulated Prices: The Case of a Public and a Private Hospital

Abstract. Hospital markets are often characterized by price regulation and the existence of different ownership types. Using a Hotelling framework, this paper analyses the effect of heterogeneous objectives of hospitals on quality differentiation, profits and overall welfare in a price‐regulated duopoly with exogenous symmetric locations. In contrast to other studies on mixed duopolies, this paper shows that, in this framework, privatization of the public hospital may increase overall welfare. This holds if the public hospital is similar to the private hospital or less efficient and competition is low. The main driving force is the single‐regulated price which induces under‐provision (over‐provision) of quality of the more (less) efficient hospital compared with the first best. However, if the public hospital is sufficiently more efficient and competition is fierce, a mixed duopoly outperforms both a private and a public duopoly due to an equilibrium price below (above) the price of the private (public) duopoly. This medium price discourages over‐provision of quality of the less efficient hospital and – together with the non‐profit objective – encourages an increase in quality of the more efficient public hospital.     

THE CASE FOR PAY-AS-YOU-GO PENSIONS IN A SERVICE ECONOMY

The elderly consume more labour‐intensive services than young individuals. This makes them vulnerable to rising costs of services due to higher wages, which can be caused by increased capital accumulation. This paper shows that in a model with a service sector, the golden‐rule capital stock is lower and dynamic inefficiency is more likely to occur than in the conventional one‐sector model. This implies that in many cases, a positive Pay‐As‐You‐Go tax maximises long‐run welfare in a service economy. Calculations based on data from the United Kingdom and the Netherlands show that the long‐run optimal degree of funding coincides with the current situation in these countries.     

State wage-payment laws, the Pension Protection Act of 2006, and 401(k) saving behavior

I show empirically that state wage-payment laws, which forbid deductions from wages and salaries without the written permission of the employee, constituted a binding constraint on firms’ choices to adopt automatic enrollment in 401(k) plans prior to 2006.     

Can national infrastructure spending reduce local unemployment? Evidence from an Australian roads program

We examine the effect of a federally-funded local infrastructure spending program on local unemployment rates. To address the likely funding endogeneity problem, we exploit variation in spending due to pork-barreling, and find that higher government expenditure on roads substantially reduces local unemployment.     

The impact of culture and ecology on cooperation in a common-pool resource experiment

Context affects decision-making in many ways. In this paper we explore differences in cooperation behaviour between communal farmers in Namibia and South Africa, who share the same ethnic origin but have had different historical and ecological constraints. We report on a series of field experiments based on a common-pool resource model. Our experimental design is framed according to the grazing situation in semi-arid rangelands. Dependent on the behaviour in previous rounds, participants are facing different states of resource availability with varying need to cooperate, coordinate and to be patient. While only 4% of the grazing areas in South Africa remain in good quality, Namibians achieve a level of 42%. We analyse the different experimental states and find that Namibians behave in all states more cooperatively. We argue that the large difference between the two regions is due to a combination of different historical developments and ecological preconditions: Namibian resource users have a longer experience in cooperative resource management and intact traditional norms. Moreover, the real-life payoffs to cooperation are higher in Namibia stemming from ecological factors.     

Agriculture production versus biodiversity protection: The impact of North-South unconditional transfers

The purpose of this paper is to explore whether international income transfers can improve or worsen the global level of biodiversity and global social welfare by changing the relative contributions to biodiversity protection and to agricultural production. Because of the public good nature of biodiversity, Warr's neutrality theorem suggests that such transfers may have no effects at all (Warr, 1983). A model is developed, based on the simplifying assumption that northern countries have little biodiversity whereas southern countries are endowed with natural capital in the form of (generally unspoilt) biodiversity-rich land. Southern countries allocate optimally land and capital to two competing productive activities, agriculture and eco-tourism. When transfers are organized from the North to the South, we show that Warr's neutrality theorem collapses. Transfers can either reduce or increase the natural capital in the South, depending on some empirically verifiable hypotheses concerning the characteristics of the eco-tourism and agricultural production functions. In addition, we demonstrate that welfare improvements can be obtained even with reductions in the level of biodiversity.     

Income taxes, spending composition and long-run growth

The focus of this paper is threefold. First, it reexamines the impact on long-run growth of changes in flat-rate income taxes when a fraction of total government expenditures is used to provide public services that affect the productivity of privately held inputs. Second, for a given tax policy, this paper studies the impact of government expenditure composition on the rate of economic growth. Third, since demographics follow an overlapping generations structure and fiscal policy affects the economy's productivity, the paper features the role of productivity as a means of redistributing income across generations. The economy is analyzed numerically and policy experiments are carried out.     

Deregulation, market power and risk behaviour in Spanish banks

This paper provides empirical evidence on the effects of regulatory changes in the market power of Spanish banks. It also analyses the response of banks, in terms of risk-taking behaviour, as a result of a reduction in economic profits. We find that liberalisation measures have increased competition and eroded banks’ market power. We observe that banks with lower charter values tend to have lower equity-assets ratios (lower solvency) and to experience higher credit risk. The last evidence is new in the literature and calls for strengthening regulatory concerns about credit risk management by banks in situations of increased competition.     

Redistribution as a selection device

This paper studies the role of the wealth distribution for the market selection of entrepreneurs when agents differ in talent. It argues that the redistribution of initial endowments can increase an economy's surplus because more talented individuals get credit for their risky investment projects. Moreover, the redistribution of initial endowments may lead to a Pareto-improvement although all agents are non-satiable. An agent's entrepreneurial ability is his private information and there is moral hazard in production. I find conditions such that unproductive rich entrepreneurs crowd out productive poor ones on the capital market. Then redistribution of initial endowments may lead to a new equilibrium where market participants are better informed about the entrepreneurs’ ability. The new equilibrium is characterized by (i) the selection of better entrepreneurs, (ii) a higher riskless rate of return on capital, (iii) lower repayments of successful entrepreneurs to their creditors and (iv) the fact that all agents are better off.
