The article presents a review of current theoretical and empirical approaches to sex work, followed by the presentation of an original theoretical framework (Della Giusta et al., 2006), which is tested with an econometric model of the characteristics of demand for sex services by a sample of clients of street sex workers in the US. We present findings in relation to stigma and the relationship between paid and unpaid sex that corroborate our model's hypotheses and are in line with findings from other empirical studies. Furthermore, we identify in our sample two diametrically opposite profiles: one for clients whom we label ‘experimenters’, and one for more experienced ones that we name ‘regulars’, we also estimate attitudes toward risk, and draw implications in terms of both policy and future theoretical and empirical research.  相似文献

This article identifies the effects of both own and spouses' education levels on individual economic satisfaction for European households. To that end, it estimates several specifications based on the family collective approach, for each of the 14 EU countries, by using the eight waves of the European Community Household Panel, 1994–2001. After demonstrating that the IV Hausman–Taylor procedure is the selected estimation method in the majority of cases, the empirical results show that male and female income satisfaction significantly increases when the husband achieves higher education qualifications in the majority of European countries. However, the positive effect of the wife's higher education on female income satisfaction only appears in a very limited number of countries. Additionally, increases in individual wage and nonwage incomes generally lead to higher satisfaction levels.  相似文献

The reported analysis examines a simultaneous estimation option-based approach to forecast futures prices in the presence of daily price limit moves. The procedure explicitly allows for changing implied volatilities by estimating the implied futures price and the implied volatility simultaneously. Using futures and futures options data for three agricultural commodities, it is found that the simultaneous estimation approach accounts for the abrupt changes in implied volatility associated with limit moves and generates more accurate price forecasts than conventional methods that rely on only one implied variable.  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

The digitalization of the newspaper industry represents a significant challenge for incumbent companies to engage new technologies. Many companies in the industry have had to seek new markets through digital technologies to survive. This paper explores how one of the largest Swedish newspapers, Aftonbladet, has strategically embraced new media and new markets. We report a decade of engaged scholarship based on interviews and archival analysis that covers 20 years of strategic acts at the company. We consider this effort as a case of organizational ambidexterity under digitalization. The analysis seeks to extend theoretical understanding of the interrelationships between strategic intent and technological choice. The paper contributes to the understanding of ambidexterity under digitalization by theoretically framing it in terms of strategic acts. The research suggests that digitalization implies a more complex ambidexterity interrelationship between old and new markets and technologies. As digitalization enables the loosening of previously tight couplings, the clear theoretical distinction between old and new, and critically, the unproblematic transition, is brought into question. The paper suggests replacing the notion of an orderly shift from the old to the new with ambidexterity under digitalization as a duality of both old and new undergoing continual reconfiguration.  相似文献

The interactions between customers and organizations have been regarded as a core aspect in cocreating and developing new products and practices. The current study explores these interactions in the context of citizens and nonprofit organizations. The study comprises two parts: (a) a qualitative approach using interviews and the analysis of social networks to better understand the organization's social media marketing practices and corresponding outcomes and (b) a quantitative approach to analyze antecedents and outcomes of trust and being committed to participate in a nonprofit organization such as Amnesty International. From the qualitative approach, the findings highlight that Amnesty International uses social media (Facebook) to share information, and citizens tend to consider sharing posts, but they do not express new ideas or interact with the organization. These findings contribute to structure the model analyzed in the second stage of the research. Regarding the qualitative approach, the results show that organizational credibility is the most significant driver of trust followed by communicative ability. Affectively commitment to participation and relationship perception act as outcomes of overall commitment.  相似文献

The transition process in Central and Eastern Europe was associated with growing environmental awareness. This paper analyses the determinants of pollution abatement and control expenditure at plant level in the case of Romania using survey data and a multilevel regression model. Our findings suggest that, although Romania has improved its environmental performance, formal and informal regulations are still only partially developed owing to the difficulties of economic transition, and heterogeneity across regions remains considerable.  相似文献

This paper re‐examines the relationship between stock market development and economic growth. It provides a theoretical basis for establishing the channel through which stock markets affect economic growth in the long run. It examines the hypothesis of endogenous growth models that financial development causes higher growth through its influence on the level of investment and its productivity. The empirical part of this study exploits techniques recently developed to test for causality in VARs. The evidence obtained from a sample of four countries suggests that investment productivity is the channel through which stock market development enhances the growth rate in the long run.  相似文献
