Corporate Ethics Initiatives As Social Control

Efforts to institutionalize ethics in corporations have been discussed without first addressing the desirability of norm conformity or the possibility that the means used to elicit conformity will be coercive. This article presents a theoretical context, grounded in models of social control, within which ethics initiatives may be evaluated. Ethics initiatives are discussed in relation to variables that already exert control in the workplace, such as environmental controls, organizational controls, and personal controls.     

Effluent fees and market structure

This paper explores the efficiency properties of a system of effluent fees in a mixed economy in which polluting agents take a variety of organizational forms: private monopoly, the managerial firm, regulated firms, and public bureaus. The analysis, including some crude empirical estimates, suggests that the welfare gains from pollution control are likely to dwarf in magnitude the potential losses from the various imperfections in the economy. The tentative conclusion is that the case for a system of fees that is invariant with respect to organizational form is not seriously compromised by likely deviations from competitive behavior.     

Alcoholic beverage legislation: Harmonizing EEC laws

This article outlines the range of non-tariff obstacles to intra-EEC trade in alcoholic beverages. It describes the response of EEC institutions vizàviz harmonization of laws and European Court jurisprudence. The implications of the now famous ‘Cassis de Dijon’ court ruling are discussed and the paper concludes with tentative suggestions on the direction of future EEC efforts to create a common market for alcoholic beverages.     

Inflation, government transfers, and optimal central bank independence

The problem of monetary policy delegation is formulated as a two-stage non-cooperative game between the government and the central bank. The solution to this policy game determines the optimal combination of central bank conservatism and independence. The results show that the optimal institutional design always requires some degree of central bank independence and that there is substitutability between central bank independence and conservatism. The results also show that partial central bank independence can be optimal and that there are circumstances under which it is optimal for the government to appoint a liberal central banker.     

Bioenergie – Beitrag zum heutigen und zukünftigen Energiesystem

The introduction and establishment of renewable energies is still discussed intensively with the focus on climate-neutral coverage of the global energy demand. In this regard it is a valid option to use biomass as a feedstock. Already today biomass contributes significantly to cover the energy demand in the global energy system. Therefore, the present and future global bioenergy potentials are investigated in the following and compared to the respective biomass use. The results show, amongst others, that the share of biomass for heat, electricity and fuel production will increase worldwide until 2030, although the availability of biomass for energy production is likely to decline in the future.     

Insurance of Household Risks and the Rebalancing of the Chinese Economy: Health Insurance,Health Expenses and Household Savings

This paper studies the effects of a public insurance system, the New Cooperative Medical Scheme (NCMS) on household savings in rural China. We develop a theoretical model in which we explain the impact of health insurance on savings through the impact of health insurance on out‐of‐pocket (OOP) health expense given the household level of wealth and seriousness of illness. We test the model empirically using data from the China Health and Nutrition Survey. We run endogenous and exogenous quantile regressions to evaluate the effects of NCMS participation on the distributions of household savings and OOP health expense. The impact of NCMS varies with the seriousness of illness. The NCMS induces an increase in OOP health expense for mild illness and, inversely, a decrease in health payments for more serious illnesses. The NCMS also leads to a higher incidence of catastrophic healthcare spending. The impact of the NCMS, given a certain state of illness, also varies with the household level of wealth. Poor households face health expense for both mild and serious illnesses. As the NCMS has opposite effects on the OOP expense for these two kinds of illness, we observe no effect on poor households’ precautionary savings. Because the decrease in OOP health expense for mild illness is larger for less poor households, the NCMS induces a decrease in their savings. For the most affluent households, the higher decrease in OOP spending on most moderate illness is dominated by a sharp increase in catastrophic expense, causing an increase in savings. To significantly reduce household savings and enhance household consumption, the NCMS has to offer better coverage against both serious and catastrophic health risks.     

Do market-concentrated airports propagate more delays than less concentrated ones? A case study of selected U.S. airports

Airport congestion and widespread passenger discontent with airlines' poor on-time performance have recently led the Federal government to reduce peak-time operations at large airports such as Chicago O'Hare and New York John F. Kennedy. This paper proposes a methodology to compute delay propagation based on the discrete Fourier transform (DFT) at a sample of ten U.S. airports in summer 2000, 2007 and 2008. The sampled airports are different in terms of size, location and index of concentration.In this research, a flight is considered to be late if it arrives more than fifteen minutes past its schedule. Delay propagation is defined as the hourly ratio of two amplitudes: the one of late arrivals at a sampled airport to that of late arrivals at the final destinations served from that same sampled airport. The purpose of this study is to determine whether delay propagation differs at market-concentrated airports from less concentrated ones. Based on nonparametric tests and proximity analysis, there is no clear evidence that market-concentrated airports are different from less concentrated ones in terms of propagated delays.
