Anecdotal evidence suggests that producers of information products (TV programs, movies, computer software) may respond to potentially cost-saving technological change by increasing, rather than reducing, their total production investments in the ‘first copy’ of each product, possibly at the expense of product variety. Comparative statics show that under reasonable assumptions about consumer demand and production technology, competitive firms in a monopolistically competitive industry are in fact induced to increase first-copy investments as a result of either what we define as ‘quality-enhancing’ or ‘cost-reducing’ types of technological advance, whereas product variety either falls or stays the same. Results suggest that contrary to often held expectations, potentially cost-saving technological advances in information industries may result in greater market concentration.  相似文献

This study examines the nonlinear impacts of four country risk indices on the debt‐growth nexus for 61 countries in a panel data framework. Our results show evidence of the different debt‐growth nexus under the different degrees of country risk. Under a high‐risk environment, a country's economic growth is harmed by raising its public debt. The negative effects public debt has on economic growth become weak under low political and financial‐risk environments, while an increase in public debt could help to stimulate economic growth under low composite and economic risk environments. In addition, the differences of countries' income and debt levels also lead country risks to have different effects on the debt‐growth nexus, suggesting that a country should borrow appropriately based on its current risk environments while improving economic performance.

We compare two reforms aimed at reducing road accidents in Italy. The Penalty Points System (PPS) provides drivers with a score and curtails points after infractions. The license is temporarily suspended when points are exhausted. Losing points is easy, but the penalty is mild. The Road Homicide (RH) introduces heavy penalties in the rare event of injuries and/or fatalities. In terms of probability and intensity of the penalty the two policies are therefore diametrically opposed. We find that injuries and fatalities decrease more with PPS than with RH. Comparing costs and benefits, we conclude that strong penalties are not beneficial. (JEL D91, K14, K42, R41)  相似文献

ABSTRACT 1 : In 2001, the Belgian government introduced a ‘service voucher’ scheme in the field of domestic (housework) services, following a quasi‐market mechanism which fosters competition between providers of different types as regards sector (for‐profit, public, third sector) and mission (seeking profits, home care provision to vulnerable groups and work integration of the unemployed). Empirical evidence suggests that third sector organizations focusing on a social mission recognized by a tutelary regulation are the best performing with regards to the quality of jobs and service organization, leading to a better ‘triangulation’ of the service relationship. On the other hand, for‐profit providers, especially temporary work agencies, seem to favour their capacity of adaptation to the desiderata of their clients and costs’ minimization to the detriment of the quality of jobs which are made as flexible as possible.  相似文献

One of the key features of our economies consists of the coexistence of different technologies supplying similar products and services. We often observe that an old technology is improved when a new one appears; behind this process of improvement often lies an intentional research activity. There thus begins a competition between the two technologies whose performances are improved via R&D. We focus our attention on this competition process and supply a formal model, based on the optimization of R&D expenditure of both technologies, which can describe the dynamics of the delayed overtaking of the new technology over the old one.  相似文献

This paper explores an issue that arises in the delegation process. The paper shows that a myopic central banker, one who treats expectations as constant in setting discretionary policy, can replicate the behaviour of output and inflation under policy from a timeless perspective. For that to happen, society must delegate a price level target or a speed limit policy to a central banker who is more weight-conservative than society.  相似文献

Income inequality in Germany has been continually increasing during the past 20 years. One cause of this development, among others, could be structural shifts in household formation due to long‐term societal trends. These affect per capita incomes, which has repercussions for the income distribution even if wages remain constant. The aim of this paper is to quantify the proportion of changing household structures in the increase in inequality. We find that the growth of the income gap in Germany (for both East and West from 1991 to 2007) is indeed strongly related to changes in household structure and employment behavior, and a large part of this increase is compensated by the welfare state.  相似文献

Using data from the National Longitudinal Study of Adolescent Health, this study examines the relationship between teenage binge drinking and three measures of academic performance: grade point average, out-of-school suspensions, and unexcused absences from school. While ordinary least square estimates show that binge drinking is associated with diminished academic performance, individual fixed-effects estimates suggest that much of this relationship can be explained by unmeasured heterogeneity. After controlling for individual fixed effects and for changes in drug use, psychological well-being, and time preference, binge drinking has a much smaller and often statistically insignificant effect on school performance.

The purpose of this study is to analyze whether previous results describing the effect of uncertainty of outcome on match attendance in team sports have been driven by heterogeneity in fan demand. We apply censored quantile regression methods and place particular emphasis on the relationship between match uncertainty and attendance demand, as previous results are highly ambiguous. This is more surprising, as each season association and league officials continue to spend millions on enhancing this uncertainty. We also control for season ticket holders, who are unlikely to be influenced by match specificities. Based on data from German soccer, our results indicate that fan demand shows heterogeneity across quantiles and that increasing match uncertainty of outcome exclusively benefits teams who already face strong attendance demand.

Using a detailed survey on Spanish workers, this paper investigates the relationship between firm size and working conditions, the extent to which firm size differences in workers' job satisfaction can be accounted for by differences in their work environment and the impact of firm size on workers' quit intentions. The results indicate that: (1) employees in larger firms face a worse work environment; (2) working in large firms significantly reduces job satisfaction when no controls for working conditions are included, but taking them into account makes differentials across size categories statistically insignificant; and (3) no systematic differences exist in intentions to quit across firm size categories, irrespective of conditioning on wages.  相似文献

It has been acknowledged that universities are key institutions in national and regional systems of innovation. This recognition has led to a rich stream of literature analysing the university–industry relationship. However, relatively little attention has been devoted to disaggregating the ‘industry’ side of this relationship and examining the costs and benefits to the disaggregated parties involved. In the present article, which draws on an analytical and empirical study from Scotland, it is suggested that it makes sense to distinguish between three kinds of firms in analysing the university–industry relationship: large national and international R&D-intensive firms, university spin-out firms, and established small- and medium-sized enterprises (SMEs) that have had little interaction with universities. The different costs and benefits facing these firms in their interactions with universities are analysed. It is concluded that the established SMEs confront relatively high costs in relating to universities. Finally, the policy implications are explored.  相似文献

Young workers in the 1990s can expect greater economic insecurity, as well as lower average earnings, compared to older workers, or compared to the youth of previous decades. The cost of greater insecurity depends upon an individual's probability of unemployment, marginal utility of income gains/losses and the extent to which individuals can smooth consumption over time by borrowing and drawing down assets. Since unemployment insurance cutbacks and higher unemployment have increased the risk exposure of youth, changes in the expected value of their income may understate utility losses as measured by the change in certainty equivalent income.
This paper uses a behavioural microsimulation model to compare the impacts of 1971 and 1994 unemployment insurance legislation and unemployment rates in Canada. It calculates both the expected value of income changes and, using a Stone-Geary utility function, the change in inequality of well-being (as measured by certainty equivalent income) for youth and for prime age workers. Both calculations reveal that youth were disproportionately affected by Canada's changing labour market environment. Very few youth have enough assets to finance consumption during spells of unemployment.  相似文献

In 2005, China abated its fixed exchange rate against the U.S. dollar and began to appreciate the Renminbi (RMB). In this paper, I explore the effect of the appreciation of the RMB on imports to the United States from China by augmenting the gravity model with the exchange rate. Using an industrial panel data set during the period 2002–2008 and controlling for the endogeneity of the bilateral exchange rate, this extensive empirical analysis suggests that the appreciation of the RMB against the U.S. dollar significantly reduced imports to the United States from China. This finding is robust to a variety of econometric methods and to coverage in different periods. (JEL F1, F2)  相似文献

The early 1990s in the United States were years of sluggish economic growth alongside a sharply lowered federal funds rate, leading analysts to conclude that monetary policy must have been rendered ineffective by external influences. One previously popular monetary policy indicator not used to analyze the period was real M2, as it was widely considered to have been distorted since the early 1980s. This paper argues that it was a serious mistake to ignore M2 in the early 1990s since it never forecast (relatively or absolutely) better and helps explains this otherwise puzzling period very well.
