Changing dynamics of the overseas marketplace for TV programming: The rise of international co-production

This article examines the recent strategy adopted by the US television production industry in coping with the changing worldwide media environment. Developments in the USA include the commercial networks' declining audience share, the increasing penetration of cable TV, and spiralling production costs; abroad, the coming of age and increased sophistication of the televesion industry and the strengthening of programme import regulations are significant. Access to foreign markets is becoming critical to the financial equation of US producers and distributors of high-budget TV programmes. International co-production is the response to the new dynamics of world-wide television programming and a product of economic necessities.     

The reliability of constructs derived from attitude-behavior theories: an application of generalizability theory in the health sector

Theories of reasoned action, interpersonal behavior and self-efficacy have been frequently used for research into health-related behavior. The present study investigated two methods for assessing the reliability of their theories' constructs: the test-retest method and generalizability theory. Firstly, it is demonstrated with a numerical example that the traditional test-retest coefficient has an anatomical link with the generalizability coefficient. Secondly, generalizability theory was applied in order to identify the number of occasions each construct must be measured to assure its reliability. This procedure was applied to the data collected in a study investigating the psychosocial factors influencing exercising and smoking behaviors among pregnant women. Measuring the constructs of direct attitude, habit, and intention on only one occasion was sufficient to ensure high levels of reliability. Moreover, reliability of the other constructs would be ensured if they were measured on more than one occasion.     

Fractional integration and business cycle features

We show in this article that fractionally integrated univariate models for GDP lead to a better replication of the main business cycle characteristics. We firstly show that the business cycle features are clearly affected by the degree of integration as well as by the other short run (AR, MA, etc.) components of the series. Then, we model the real GDP in the UK and the US by means of fractionally ARIMA (ARFIMA) model, and show that the time series can be specified in terms of this type of model with orders of integration higher than one but smaller than two. Comparing the ARFIMA specifications with those based on ARIMA models, we show via simulations that the former better describe the business cycles features of the data.Jel classification: C12, C15, C22The authors want to thank two anonymous referees for wise remarks.

Does entry improve welfare? A general equilibrium approach to competition policy

We consider a simple general equilibrium model with imperfect competition. Firms are price takers in the input market and compete à la Cournot in some or all of the product markets and their technologies display constant returns to scale. We show that an increase in the number of firms in a given sector does not always improve welfare. We also provide a characterization in terms of mark-up rates of the sectors for which entry is welfare enhancing. Our results challenge the common idea that mergers with no cost synergy are not desirable for consumers.     

A Hotelling model with a ceiling on the stock of pollution

Environmental agreements such as the Kyoto Protocol aim to stabilize the amount of carbon in the atmosphere, which is mainly caused by the burning of nonrenewable resources such as coal. We characterize the solution to the textbook Hotelling model when there is a ceiling on the stock of emissions. We consider both increasing and decreasing demand for energy. We show that when the ceiling is binding, both the low-cost nonrenewable resource and the high-cost renewable resource may be used jointly. A key implication is that if energy demand were to decline in the long run, we may supplement energy supply through ‘clean’ renewables to meet the environmental standard, but then revert back to using only ‘dirty’ fossil fuels in the future when the ceiling has become non-binding. That is, the much heralded societal ‘transition’ to clean energy resources may be short-lived.     

Fiscal policy in good and bad times

In this paper we analyze whether the effect of fiscal policy differs across the business cycle. To tackle this question, we use a regime-switching error-correction framework, where nonlinearities are only modeled in the short-run and have no impact on the long-run equilibrium. Regime specific shocks to government revenue and government purchases are identified using sign restrictions. Linear combinations of the impulse responses of these basic shocks are used to construct a deficit-spending shock and a deficit-financed tax-cut shock. We find that active spending policies have a stronger impact in recession, with multipliers exceeding unity, and should be preferred to deficit-financed tax-cuts.
