We study how managerial bargaining power affects outcomes and payoffs in a Hotelling‐type duopoly framework with restricted and unrestricted locations. We show that bargaining power only affects the distribution of the surplus between owners and managers but does not affect the locations, prices, managerial incentives, and consumer welfare. This is in stark contrast to van Witteloostuijn et al. (2007) and related contributions where bargaining power has real effects. We argue that the difference between our irrelevance result and their findings originates from the fact that their approach seems to be based on a behavioral assumption and not on microeconomic principles of owner–manager bargaining.

The purpose of this study is to examine the relationship between firm size and time-varying betas of UK stocks. We extend the Schwert and Seguin (1990)(Journal of Finance 45, 1120–1155) methodology by explicitly modeling conditional heteroscedasticity in the market model residual returns. Our results show that the time-varying coefficient is not statistically significant for both small and large firm stock indexes. We also find that accounting for GARCH effects in the Schwert-Seguin market model yields beta estimates that are markedly differently from those when conditional heteroscedasticity is ignored. Event studies that ignore conditional heteroscedasticity may bias the abnormal returns of small and large firms, thereby leading to a different conclusion regarding the significance of an information event.  相似文献

Most of the theoretical and empirical literature on the effects of unemployment insurance (UI) during the last 25 years has focused on the supply-side implications. The object of this article is to argue that much of those discussions over the disincentive effects of UI is misdirected. Our intention is to bring back to the forefront a discussion of the positive macroeconomic role played by UI net injections in stabilizing aggregate demand. Our empirical results using Canadian data for the postwar period support this Keynesian view of the stabilizing effect of UI in contemporary economies.  相似文献

This article examines project management through the lens of practice. Drawing on the literature, we develop a typological model that brings together four distinct theoretical types of project management practice. Adopting a deliberately critical perspective, we show that the first three types propose a weak conception of the logical relationship between the theory and practice of project management. In contrast, the fourth type, anchored in a pragmatist conception of the theory‐practice link, provides the potential to build strong theories of project management practice. A specific objective is to elucidate the distinct features of the fourth type of theory.  相似文献

The purpose of this paper is to analyze the relationship between democratization and technological innovation. In primis, the paper shows, through economic history, that democratization is an antecedent process (cause) to technological and economic change (effect). In particular, the primary finding is that democratization is a driving force for technological change: most free countries, measured with liberal, participatory, and constitutional democracy indices, have a higher level of technology than less free and more autocratic countries. In fact, “democracy richness” generates a higher rate of technological innovation with fruitful effects for the wellbeing and wealth of nations. These findings and predictions lead to the conclusion that policy makers need to be cognizant of positive associations between democratization and technological innovation paths in order to support the modern economic growth and future technological progress of countries.  相似文献

The purpose of this paper is to analyze the pattern and behavior of Economic Long Waves over time, using the long-wave chronologies of two driving economies, the USA and the UK. The statistical evidence seems in general to support the hypothesis that Long Waves are not symmetric and their regularity is based on longer periods of upwave than downwave (contraction-skewed), which implies a negative asymmetric path of these waves over time.  相似文献

The objective of this study is to shed light on the determinants of criminality rates in Brazil. A panel data model was estimated using Brazilian states’ data. Our main result suggests that income inequality plays an important role in the determination of the crime rate. Furthermore, there are evidence suggesting that both unemployment and urbanization rates are positively related to crime. Based on a GMM approach we find the existence of an “inertial effect” on criminality. Besides that, the GMM results show that public security spending is effective in reducing criminality rates. Contrary to the common wisdom, we could not find evidence that poverty increases violent crimes. Finally, we have evidence that income inequality Granger causes crime, but not the reverse.  相似文献

Abstract

Aim: Disease-related malnutrition (DRM) is a prevalent condition that significantly increases the risk of adverse outcomes in hospitalized patients, particularly those with critical illness. Limited data is available on the economic burden of DRM and the cost–benefit of nutrition therapy in high-risk populations in Latin America. The aims of the present study were to estimate the economic burden of DRM and evaluate the cost–benefit of supplemental parenteral nutrition (SPN) in critically ill patients who fail to receive adequate nutrient intake from enteral nutrition (EN) in Latin America.

Methods: Country-specific cost and prevalence data from eight Latin American countries and clinical data from studies evaluating outcomes in patients with DRM were used to estimate the costs associated with DRM in public hospitals. A deterministic decision model based on clinical outcomes from a randomized controlled study and country-specific cost data were developed to examine the cost–benefit of administering SPN to critically ill adults who fail to reach ≥60% of the calculated energy target with EN.

Results: The estimated annual economic burden of DRM in public hospitals in Latin America is $10.19 billion (range, $8.44 billion–$11.72 billion). Critically ill patients account for a disproportionate share of the costs, with a 6.5-fold higher average cost per patient compared with those in the ward ($5488.35 vs. $839.76). Model-derived estimates for clinical outcomes and resource utilization showed that administration of SPN to critically ill patients who fail to receive the targeted energy delivery with EN would result in an annual cost reduction of $10.2 million compared with continued administration of EN alone.

Limitations: The cost calculation was limited to the average daily cost of stay and antibiotic use. The costs associated with other common complications of DRM, such as prolonged duration of mechanical ventilation or more frequent readmission, are unknown.

Conclusions: DRM imposes a substantial economic burden on Latin American countries, with critically ill patients accounting for a disproportionate share of costs. Cost–benefit analysis suggests that both improved clinical outcomes and significant cost savings can be achieved through the adoption of SPN as a therapeutic strategy in critically ill patients who fail to receive adequate nutrient intake from EN.  相似文献

We present evidence that banking development plays a key role in technological progress. We focus on manufacturing firms' innovative performance, measured by patent-based metrics, and employ exogenous variations in banking development arising from the staggered deregulation of banking activities across US states during the 1980s and 1990s. We find that interstate banking deregulation had significant beneficial effects on the quantity and quality of innovation activities, especially for firms highly dependent on external capital and located closer to entering banks. Furthermore, we find that these results are strongly driven by a greater ability of deregulated banks to geographically diversify credit risk.  相似文献
