By using a sample of 644 manufacturing firms in four EU countries and five regions, we investigate the earliness/exporting relationship. Firstly, we examine the firm’s ability to retain LAN over time as it gets older and bigger. Secondly, we examine the role played by the firm’s decision-making structure. Our results reveal that exporting sclerosis does set in, as age and size of the firm significantly and negatively affect the earliness/exporting relationship. In addition, however, we find that centralization plays a role in the sclerotic effects of size (though only weakly for age), exacerbating their moderating effects on the earliness/exporting relationship. Our study claims to contribute to internationalization research by advancing the idea that LAN is not path-dependent but subject to liabilities. Beyond age and size, we add the more nuanced “liability of centralization” to boundary conditions for retaining LAN. Theoretical and managerial implications emerge.  相似文献

The objective of this paper is to estimate the impact of reducing carbon dioxide emissions from fossil fuel combustion activities on economic activity in Portugal. We find that energy consumption has a significant impact on macroeconomic activity. In fact, a 1 ton of oil equivalent permanent reduction in aggregate energy consumption reduces output in the long term by €6,340. More importantly, and since carbon dioxide emissions are linearly related to the amounts of fuel consumed, our results allow us to estimate the costs of reductions in carbon dioxide emissions. We estimate that a uniform standard for reducing carbon dioxide emissions from fossil fuel combustion activities would lead to a marginal abatement cost of €95.74 per ton of carbon dioxide. This is a first rough estimate of the potential economic costs of policies designed to reduce carbon dioxide emissions. At this level one may conclude that uniform, across the board reductions in carbon emissions would have a clear negative effect on economic activity. Hence, at the aggregate level there is clear evidence for a trade-off between economic performance and a reduction in carbon emissions. This opens the door to the investigation of the scope for policy to minimize the costs of environmental policy and regulation.  相似文献

Many economists criticize the concept of the composite commodity'of housing that forms the basis of modern urban economics. As a result, much empirical work has been produced that attempts to estimate the household demand for housing and locational characteristics. The purpose of this paper is to take stock of the literature. The theoretical foundations of the literature and the econometric procedures employed are analyzed and critiqued. In addition, the empirical results are examined in order to identify any patterns that exist. The principal conclusion of this survey is that the theoretical basis is sound, but the econometric applications leave much to be desired. One consequence is that the literature has produced few empirical regularities. Another is that more studies using better estimation procedures and better data are needed before it can be safely argued that the composite commodity concept is replaced by the characteristics approach.  相似文献

In this paper, we use a VAR approach to investigate the effects of public investment in transportation infrastructures on private investment, employment, and output in Portugal. Estimation results suggest that public investment crowds in private investment and employment, and has a strong positive effect on output. We estimate that one euro in public investment increases output in the long‐term by 9.5 euros, which corresponds to a rate of return of 15.9%. These figures imply that there are strong long‐term budgetary benefits from public investment in the form of increased future tax revenues. A closer look at the effects of different types of public investment uncovers the same general patterns. These results are very important from a public policy perspective. They suggest that the strategy followed by the Portuguese authorities of investing in public infrastructures is justified, both from a long‐term development perspective and a long‐term public budgetary perspective.  相似文献

With the continuing growth of the use of the Internet for business purposes, the consequences of a possible cyber attack that could create a large scale outage of long time duration becomes a more and more serious economic issue. In this paper, we construct a game-theoretic model that addresses the economic motivations for investment in added Internet security and makes a case for a possible market failure in the form of underinvestment in the provision of Internet security. This result relies on the fact that the social value derived from consumption (which is at least equal to a fraction of the surplus derived from e-commerce) greatly exceeds the revenue at stake associated with the telecommunications companies’ and ISP’s security levels. If the ratio of social value to revenue at stake to Internet providers continues to grow, the likelihood of underinvestment in security becomes higher and some form of regulation may become necessary. We discuss the difficulties associated with designing and enforcing a regulatory scheme based upon mandatory security standards.   相似文献

Do social security systems "crowd out" private transfers fromyounger to older generations? This question has generated muchtheoretical discussion, but little empirical work exists toconfirm or refute this crowding-out hypothesis. We investigatethe connection between social security and private transfersin Peru, using the Peruvian Living Standards Survey, and findthat private transfers from young to old would have been nearly20 percent higher without social security benefits. This indicatesthat the Peruvian social security system is less effective atdelivering benefits to the elderly than a simple assignmentof government expenditures would suggest. Social security'sdisplacement of private transfers, while significant, is lessthan that predicted by models with widespread altruistic transfers.  相似文献

Obesity and overweight are linked to diseases that cost society a significant amount of resources. While behavior modification can reduce the problem, instigating such lifestyle changes is an uneasy task. One potential way to reduce the problem is through the use of financial incentives. In this survey, we review the available evidence, properly emphasizing studies that credibly yield meaningful estimates of the effect of financial incentives on weight loss. We find that the scientific literature on the subject has not yet satisfactorily settled whether such a mechanism is effective at eliciting the desired behavioral and health outcomes. We therefore advocate a rigorous large‐scale randomized experiment to provide reliable estimates of the effect.  相似文献

A constitutional right to just compensation for governmental takings implies a right to a judicial review of the adequacy of the compensation. Thus, a property owner, subjected to a takings action, can threaten to litigate if he considers compensation insufficient. This paper uses a theoretic settlement-litigation analysis to demonstrate how the litigation threat influences the size of the compensation. In addition, it revises the theoretical explanation for earlier empirical findings that certain classes of property owners often receive more than market value for their property. It is also shown that the just compensation mechanism cannot guarantee efficient takings. Extending the basic model to regulatory takings, this paper demonstrates that recent changes in the judicial doctrine of when a regulation has gone too far and demands compensation has strengthened the litigation threat of property owners. It explains why political decisionmakers are moving toward settlements with terms which are increasingly defined by legislation.  相似文献
