The adoption of certain behaviors—like smoking or physical activity—is recognized as a major factor affecting health. Analyzing the social determinants of these behaviors, then, should be considered an important goal, since it may improve our understanding of the more general phenomenon of health inequalities. In this paper we analyze the association between socioeconomic status (SES) and health-related behaviors among the Italian population aged 18–74 in 2004/2005. Using large-scale sample survey data and a Weberian lifestyle approach, we first identify an ordered multidimensional space of health-related behaviors, and partition this space into a meaningful set of discrete regions representing a fine-grained taxonomy of health lifestyles. Then, we use regression analysis to determine if, and to what extent, the identified lifestyles are associated with SES. Using level of education as an indicator of SES, we find that the propensity to adopt healthier lifestyles exhibits a positive educational gradient, whereas the probability of following less healthy lifestyles is inversely associated with the level of education. We conclude that, in general, focusing on health lifestyles—i.e., on combinations of multiple health-related behaviors—instead of single behaviors may lead to a better understanding of health-related practices and their relationship with socioeconomic status. 相似文献

ABSTRACT This paper provides an empirical investigation of the impact of market orientation on firms' economic performance during the period 1998–2012 using a panel of Italian manufacturing firms. We introduce a dynamic concept of market orientation, in that we define a market-oriented firm as one that persistently undertakes product and marketing innovation, while at the same time introducing organizational changes and training efforts to manage and improve its knowledge assets over the long term. This notion of market orientation is therefore crucially related to the so-called dynamic capability approach. The related empirical model shows that being a market-oriented firm significantly affects profitability, in a framework in which this latter is simultaneously estimated with productivity, thus allowing for more precise estimates of the profit premium which is earned accordingly. 相似文献

This paper examines the relationship between cash holdings and performance in Italy over 36 years. Specifically, in light of the presence of conflicting evidence concerning the worth of cash stock, which could lead to a positive effect rather than a negative one, the role of moderating factors that can shape the magnitude of this relationship is investigated. The results show that the value of cash holdings is affected by firm‐specific characteristics, as well as factors related to the institutional context. Although other studies have analyzed moderators one at a time, this is the first work to consider how they jointly work. When the moderators are considered together, some of them become no longer statistically significant while others become even more economically and statistically relevant. 相似文献

This article presents a model of political corruption in which a briber can choose either to bribe only the incumbent party or to capture also the opposition party to sterilize its monitoring role. The analysis also explores interparty collusion, media independence, and political contestability. The model suggests that policies aiming to strengthen the role of minorities can produce ambiguous effects as they may induce bribers' avoidance behavior. Reputational sanctions appear to be less effective than criminal ones, although political contestability increases their deterrence effect. Paradoxically, harsh criminal sanctions may induce tacit collusion because minorities highly regard their outcomes once in power. 相似文献

Many nations have undergone significant trade liberalization even as they have increased their use of contingent protection measures. This raises the question of whether some of the trade liberalization efforts, at times accomplished through painful reforms, have been undone through a substitution from tariffs to non‐tariff barriers. Among the new forms of protection, antidumping is the most relevant. This paper examines whether the use of antidumping is systematically influenced by the reduction of applied sectoral tariffs in a sample of 29 developing and six developed countries from 1991 through 2002. Evidence is found of a substitution effect only for a small set of heavy users of antidumping among developing countries. There is no similar statistically significant result for other developing countries or developed countries. Robust evidence is also found of retaliation and deflection effects as determinant of antidumping filings across all subsamples. 相似文献

The aim of this article is to analyse empirically whether the level of institutional quality influences how financial development affects poverty for a sample of developing countries covering the period from 1984 to 2012. Using an interaction term constructed as a product between financial development and institutional quality we find that the pro-poor impact of financial development decreases as the quality of institutions rises. Such a differential effect can be ascribed to the capacity of banks to provide functions that mimic those performed by an institutional framework that works well. The results of this article can be used for policy management. 相似文献

We propose here a theory of cylindrical stochastic integration, recently developed by Mikulevicius and Rozovskii, as mathematical background to the theory of bond markets. In this theory, since there is a continuum of securities, it seems natural to define a portfolio as a measure on maturities. However, it turns out that this set of strategies is not complete, and the theory of cylindrical integration allows one to overcome this difficulty. Our approach generalizes the measure-valued strategies: this explains some known results, such as approximate completeness, but at the same time it also shows that either the optimal strategy is based on a finite number of bonds or it is not necessarily a measure-valued process.Received: November 2002, Mathematics Subject Classification:
