Free entry in successive oligopolies

In the present paper, we propose an extension of Spengler's (1950) analysis of successive oligopolies, to study the effects of entry in the downstream and upstream markets. Free entry is analyzed using replica economies à la Debreu and Scarf (1963) . We find that free entry may have different effects in the upstream and in the downstream market. Namely, the usual convergence of the price to the corresponding marginal cost only occurs in the downstream market.     

Transparenz im Journalismus

The transparency that journalists and newsrooms can produce for their audience has long been regarded as a rather marginal criterion for journalistic quality. But new transparency models??due to the interactivity, immediacy, archiving capacity and the absent limitation of space in the internet??offer greater potentials than classical instruments in print and broadcasting. In comments, web videos, blogs, twitter feeds and social networks, journalists discuss with users and publicly account for editorial decisions. Transparency is fashionable in the digital public sphere; its evaluation, however, is not clear, but ambiguous and complex. This paper conceptualizes (self-)transparency and qualitatively classifies the available instruments in a three-dimensional matrix model. This is to facilitate the analysis of problematic areas and potential conflicts: Newsrooms demonstrating open self-reflection dismiss the ideal of ??objective journalism??. Yet, transparency is not only an ethical demand, but is also supposed to strengthen trust in journalistic products because it permits quality evaluations by the audience. An experiment shows, for the first time, that self-transparency has an effect on trust in some aspects but not as a basic principle. Analysing this interdependency, we have to distinguish between transparency of process and of product as well as between different media.     

??ber Terroristen und Spitzensportler

Islamophobia is more strongly developed in East Germany compared to the western part of the country. Given the lack of personal contact with Muslims in East Germany, islamophobia is probably strongly influenced by media coverage. For this reason, the coverage of two East German regional newspapers, Nordkurier and Volksstimme, is analyzed against the theoretical background of a conjunction of the social-psychological stereotype content model with the communication-scientific concept of framing. Using content analysis and latent class analysis, two so-called stereotype frames were identified. Two thirds of all Islam-related articles use the ??cold and harm frame??. Here, Muslims are often blamed for the lethal consequences of terrorist action, their behaviour is evaluated as cold or immoral, and military interventions against them are discussed. On the other hand, one third of all Islam-related articles belongs to the ??competence and cooperation frame??. Competence is ascribed to Muslims as their success in artistic, athletic or political activities is recognized and other actors?? interest in cooperation in these areas is emphasized. Whereas the ??cold and harm frame?? probably promotes medial segregation, the ??competence and cooperation frame?? is representing an assimilative model of media integration.     

Social Network and Weight Misperception among Adolescents

It is recognized that public health intervention targeted toward changing lifestyle behaviors to reduce overweight status is a considerable challenge. It is important that individuals recognize their overweight status as a health risk in order for an effective change in lifestyle behaviors to occur, and growing evidence suggests that actual weight and perception of weight status often do not match, especially among adolescents. In this article, we explore the extent to which exposure to heavier peers and parents affects misperception of their own weight status by adolescents. Using data from a nationally representative sample of adolescents, we estimated instrumental variable models with school‐level fixed effects to account for bidirectionality of peer influence and environmental confounders. Our results indicate that individuals who live in an environment that exposes them to overweight/obese parents and heavier peers tend to misperceive their weight status and think of themselves to be of lower weight than they actually are. Our analysis also revealed differential effects by gender and type of peers.     

Foreign Investors in The Netherlands: Heterogeneous Employment and Productivity Effects

Recent academic research suggests that the effects of inward foreign direct investment for productivity and employment may vary across foreign investors with different characteristics. Using a newly created dataset that integrates micro-level information from The Netherlands Foreign Investment Agency and Statistics Netherlands, this paper explores the role of several of these characteristics, including e.g. the country of origin, activities and tasks, age and strategic role of foreign affiliates in The Netherlands in the 2000–2007 period. Our analysis shows that important employment and productivity differences exist for nearly all these dimensions.     

Effects of Free Trade on Women and Immigrants: CAFTA and the Rural Dominican Republic

We construct a disaggregated rural economywide model with a focus on gender and immigration as well as on the allocation of time to wage work, household production activities, and housework (reproduction). We use this model to simulate the impacts of the Dominican Republic-Central American Free Trade Agreement (DR-CAFTA) on rural incomes and welfare in the Dominican Republic. We find that elimination of agricultural import tariffs hurts both agricultural and non-agricultural households, via adverse factor-market effects, but impacts vary substantially by workers’ gender and country of origin. Females and Haitian immigrants tend to fare better than Dominican males, and there are ramifications for both market and non-market activities.     

UK World War I and interwar data for business cycle and growth analysis

This article contributes new time series for studying the UK economy during World War I and the interwar period. The time series are per capita hours worked and average capital income, labor income, and consumption tax rates. Uninterrupted time series of these variables are provided for an annual sample that runs from 1913 to 1938. We highlight the usefulness of these time series with several empirical applications. The per capita hours worked data are used in a growth accounting exercise to measure the contributions of capital, labor, and productivity to output growth. The average tax rates are employed in a Bayesian model averaging experiment to reevaluate the Benjamin and Kochin (J Political Econ 87:441–478, 1979) regression.     

Medical Malpractice Liability and Physician Migration

This paper uses national data on individual physicians and two control groups to provide evidence on the extent to which each of five medical malpractice reforms impacts the decision to move one's medical practice to another state. We find robust evidence that states that have implemented noneconomic damage caps experience less out-migration of physicians than states that do not have these reforms. In addition, we find some evidence that joint and several liability reforms and patient compensation funds also impact the migration decisions of physicians.
