Democracy and trade: an empirical study

The theoretical discussion on globalization has suggested that there are linkages between democracy and trade, although the direction of influence is less certain. Formal empirical studies remain scarce, and have often focused on the question of whether democratic regimes influence trade policy, as opposed to the actual relationship between democracy and trade. This paper seeks to answer the question, “Do democracies trade more?” by applying the gravity equation to a large dataset of bilateral trade data for the period 1948–1999, while taking into account the role of democracy. It finds that democracy is positively related to trade flows, but only after controlling for trade pair heterogeneity. In addition, it makes the case for studies of this nature to draw a distinction between trade flows in the pre- and post-1990s period of rapid democratization as well as between developed and developing countries.     

Survey error in an international context: an empirical assessment of cross-cultural differences regarding scale effects

Likert-type of questions are prone to differences in response styles. The aim of the present study is to examine possible cross-cultural differences regarding scale effects resulting from different answer categories. This study aims to extend the literature on scale effects to a foreign language. An English questionnaire containing two experimental questions was presented to students enrolled in international MSc programs. In addition to the experimental questions, the questionnaire contained filler questions, demographic questions, and questions on English proficiency. The questionnaires differed only from each other with respect to answer categories and scale presented with the experimental questions. The questionnaire was presented during class, to 526 students coming from over 70 different countries. These countries were classified according to continent and language into 10 groups of which nine were large enough to be included in the analysis. After considering possible confounding factors, like age, gender, English language proficiency, and disciplinary background, scale effects were shown to be present across groups of countries. These differences seriously affect rankings. Concludingly, scale effects persist in non-native language questionnaires, and the effect sizes differ across cultures.     

The implications of efficiency differences in sustainable development: An empirical study in the consumer product industry

Firms often invest in sustainable development projects to improve their environmental and societal performance. Given the broad spectrum of these projects and limited resources, managers face challenges in determining where to improve (e.g., improving water consumption and reducing carbon footprint). The study examines the connection between environmental performance and firm performance from a new angle to help managers make informed decisions. The study examines firms in the consumer product industry regarding their efficiency in the operational aspect, the resource-related environmental aspect, and the climate-related environmental aspect. It then employs panel data models to investigate the implications of efficiency differences across these aspects on firms' financial performance and business risk. The results indicate that the effects of these differences are adverse in general. Additionally, the relationship between the operational and environmental efficiency difference and financial performance is in an inverted-U shape. The study contributes to the literature by offering theoretical support and empirical evidence for the balanced portfolio approach in managing multiple environmental concerns. The study findings also provide managerial guidelines for decision-making. To gain a greater benefit, managers should aim to minimize the performance differences across multiple environmental aspects and manage a subtle balance between operational performance and environmental performance.     

Using nonparametric methods in social surveys: an empirical study

The most common form of data for socio-economic studies comes from survey sampling. Often the designs of such surveys are complex and use stratification as a method for selecting sample units. A parametric regression model is widely employed for the analysis of such survey data. However the use of a parametric model to represent the relationship between the variables can be inappropriate. A natural alternative is to adopt a nonparametric approach. In this article we address the problem of estimating the finite population mean under stratified sampling. A new stratified estimator based on nonparametric regression is proposed for stratification with proportional allocation, optimum allocation and post-stratification. We focus on an educational and labor-related context with natural populations to test the proposed nonparametric method. Simulated populations have also been considered to evaluate the practical performance of the proposed method.     

Determinants of hierarchical structure in industrial firms: an empirical study

The paper investigates implications of different theoretical models for hierarchical structure. A sample of 6,578 firms in the Brazilian manufacturing industry is considered and explanatory factors pertaining to structural characteristics, network technology, technological innovations, managerial innovations and incentive mechanisms are investigated. Important joint effects are detected for all groups of variables in partial contrast with the related previous literature. Moreover, one detects significant joint effect of the newly considered group of incentive variables. The evidence in terms of individual effects is largely consistent with the predicted effects from the theoretical literature.     

Freedom and gross in-migration: an empirical study of the post-great recession experience

Determinants of migration, including policy variables such as tax rates, have been extensively studied by regional scientists over the past several decades. The development of the Economic Freedom of North America Index has allowed researchers to test the relationship between migration patterns and economic freedom, with recent studies finding that net in-migration is positively related to economic freedom. Using a new cross-section measure of economic and personal freedom at the state level, we investigate the relationship between gross in-migration and economic freedom on the one hand and then between gross in-migration and total freedom on the other hand. This empirical study of domestic U.S. migration during the post-Great Recession period finds clear evidence that migrants prefer to move to those states affording higher levels of economic freedom and higher levels of total freedom.     

Repatriation of European female corporate executives: an empirical study

The increased internationalization of business in recent years has made the understanding of international human resource management problems more important for executives in multinational companies. In recent years, researchers have paid considerable attention to the issues of adjustment of managers to international assignments. Interestingly, comparatively little research has been undertaken on the topic of repatriation, i.e. re-entry and readjustment of international managers and their families to their home countries. Despite the growth of women in international management there are very few studies that document the repatriation experiences of female international managers. In particular, very few studies have been conducted outside North America on the topic of repatriation of female corporate executives. This paper reports on the experiences of re-entry to home organizations and home countries by an exclusively senior sample of female international managers in Western Europe. Based on extensive empirical research, the findings establish that the repatriation phase of the international career move may be even more stressful than expatriation. The findings also establish that female international managers experience more difficulties than their male counterparts because of their pioneering roles. Finally, the paper suggests that home-based mentors and access to networks while abroad are important factors in contributing to the successful repatriation of international managers. The research findings make a theoretical contribution, not only to the analysis of gender and international human resource management but, also, to wider debates within the contemporary women in management and career theory literatures.     

Management and employee involvement in achieving an environmental action-based competitive advantage: an empirical study

The objective of this work is to conduct an empirical study that shows whether certain management and human resource factors influence the achievement of an environmental action-based competitive advantage in a company. To this end, we have taken a sample of 110 factories. Management's deep involvement and its strategic integration, as well as employee motivation and participation, have a positive impact on the achievement of an environmental action-based competitive advantage in a company.     

Options and earnings announcements: an empirical study for the European Options Exchange

In this paper we give an introduction in option pricing theory and explicitly specify the Black-Scholes model. Although market participants use this and similar models to price options, they violate one of the fundamental assumptions of the model. They do not set a constant value for the volatility of the underlying asset over time, but change the volatility even during a day. By means of event study methodology we investigate the volatility of the underlying asset and the volatility implicit in option prices around earnings announcements by firms. We find that the volatility in option prices increases before the announcement date and drops sharply afterwards. The volatility of the underlying stocks is higher only at the announcement dates and we do not observe a higher volatility around these dates. Hence, the constant volatility of the underlying asset, which is one of the assumptions in the Black-Scholes model, does not hold. However, the market seems to correctly anticipate the change in volatility, by correcting option prices.     

Human resource management and business strategy links: an empirical study

Over recent years there has been an increasing interest in the field of human resource management. Currently, the literature encourages the consideration of human resources as strategic factors, not only because they play important role in strategy implementation, also because they are beginning to be reckoned as sources of sustainable competitive advantage. Relationships between human resource management and strategy have been studied from different perspectives. This article focuses on one of them. It examines matches between human resource practices and types of business strategy. The question addressed is: do human resource management practices vary with business strategy? To answer this question, empirical research was developed. Using data collected from 200 Spanish companies, this paper demonstrates significant associations between some human resource practices and business strategy in companies. Reported results support some of the previously established relationships. Implications for future research are discussed.     

Corruption,regulation, and growth: an empirical study of the United States

This paper investigates whether the costs of corruption are conditional on the extent of government intervention in the economy. We use data on corruption convictions and economic growth between 1975 and 2007 across the US states to test this hypothesis. Although no state approaches the level of government intervention found in many developing countries, we still find evidence for the “weak” form of the grease-the-wheels hypothesis. While corruption is never good for growth, its harmful effects are smaller in states with more regulation.

Developments in non-expected utility theories: an empirical study of risk aversion

This paper investigates different developments in non-expected utility theories. Our focus is to study the agent’s attitude towards risk in a context of monetary gambles. Based on simulated data of the “Deal or No Deal” TV game show, we first compare the performance of the expected utility model versus a loss-aversion model. We find that the loss-aversion model has a better performance compared to the expected utility model. We then study the attitude towards risk according to two parameters: the relative risk aversion coefficient defined over the value function and the probability weighting coefficient proposed by the Cumulative Prospect Theory. We find evidence for probability weighting being undertaken by contestants reflecting less risk aversion over large stakes. We also explore the performance of two models of rank-dependant utility: the Quiggin (1982) and the power probability weighting models. We find that the probability weighting coefficient is still significant for both models. Finally, we integrate initial wealth into the contestants’ preferences function and we show that the initial wealth level affects the estimates of risk attitudes.     

Turnover propensity and its causes among Singapore nurses: an empirical study

Nurse turnover has been a serious challenge to the efficiency and effectiveness of any health-care delivery system. Various antecedents of turnover are examined in this study in attempt to identify the most critical causes of the problem. One hundred and eighty nurses from a large hospital in Singapore participated in the survey. The results show that a) stress strikes throughout different stages in turnover development; b) professional commitment is a significant cause of turnover cognition, but not turnover intention; and c) organizational commitment and supervision satisfaction are among the top predictors of turnover intention. These results deviated from the apprehension of many health administrators about the causes of the nursing turnover, thus provided clues as to how to mitigate the problem. And, as they were compatible with the results of studies on Canadian and American nurses, these results contributed to the empirical generalization process. The implication of the findings is discussed in the paper.     

Understanding peak avoidance commuting by subway: an empirical study in Beijing

Congestion is a major problem for peak-hour commuters in the Beijing subway system, as it leads to long queuing times and overcrowded vehicles. This paper explores to what extent peak travel can be reduced by providing incentives for peak avoidance. In a stated preference study, travellers’ responses to two financial and two non-financial incentives were measured, and factors increasing or limiting the response were identified. Our results suggest that all four incentives can be reasonably effective tools and the financial incentives seem to have a slightly stronger effect than the services and credit-for-gifts-based scenarios. Ordered logit models indicate that various factors influence people’s receptiveness of incentives for peak avoidance which relate to the ease of change or presence of alternatives and receptiveness to incentives. Both theoretical and policy implications are concluded that the proposed factors and incentive system can help solving the subway congestion in Beijing.

Rural entrepreneurs and institutional assistance: an empirical study from mountainous Italy

Despite the recognition of entrepreneurship as one of the main determinants of rural economic development, empirical research in this field is relatively sparse. Thus, there is little evidence on the role and function of rural entrepreneurs, the driving force behind the birth, survival and growth of rural enterprises. The present work aims at providing a contribution to filling this gap in knowledge. We present and analyse the results emerging from a questionnaire submitted to a sample of 123 rural entrepreneurs and businesses in a mountainous area of central Italy. In particular, we test for six hypotheses concerning the correlation between different factors, reflecting entrepreneur and business-specific characteristics, and the adoption of instruments of institutional assistance. Entrepreneur's and business's variables are related to (1) entrepreneurial human capital; (2) entrepreneur's local knowledge and social capital; (3) firm's size; (4) entrepreneur's age; (5) firm's age; and (6) busines's sector of activity. Empirical results largely support the importance of variables taken into consideration in explaining differences in the adoption of institutional assistance among businesses of the sample. In the light of our empirical findings, we also examine and propose potential policies for fostering entrepreneurship and the development of the rural region under study.
