Does oil corrupt? Evidence from a natural experiment in West Africa

This paper explores the oil discovery announcements in Sao Tome and Principe (1997-1999) to assess the role of natural resources in determining corruption. For this purpose, we use a natural experiment framework which contrasts Sao Tome and Principe to Cape Verde, a control West African country sharing the same colonial past and important recent economic and political shocks. Our measurement is based on tailored household surveys we conducted in both island countries. The unique survey instrument was retrospective and used personal histories to elicit memories from the respondents. We analyze changes in perceived corruption across a wide range of public services and allocations. We find clearest increases on vote buying, education (namely in the allocation of scholarships) and customs, ranging from 31 to 40% of the subjective scale. We interpret these findings as symptoms of increased competition for core state resources.     

Measuring Stakeholder Integration: Knowledge,Interaction and Adaptational Behavior Dimensions

Stakeholder Theory combines the pursuance of business goals and responsibility toward a firm’s stakeholders. Despite the wealth of research on Stakeholder Orientation, we still have much to learn about specific measurements for several related constructs. In this study, we draw on two samples of 129 and 151 Spanish firms, respectively, to investigate CEOs’ perceptions on Stakeholder Integration (SI), leading to the identification of three dimensions of the construct. In this respect, our study suggests that Knowledge of Stakeholders, Interactions between a firm and its stakeholders, and the adaptation of a firm’s behavior to stakeholders’ demands constitute the main dimensions of SI. This construct has the potential to connect the stakeholder and strategy literatures.     

Governance of Knowledge‐Intensive Firms in the Modern Market Economy

We model contracting for joint production between workers and shareholders when investment in knowledge is non‐verifiable and the resulting specific human capital embedded in the workers is non‐tradable. The model explains how the effective cost of human capital services will vary depending on whether the investment in knowledge is financed by the workers or by the shareholders. We apply the results of the modeling to identify which firms are expected to gain and which to lose from posted trends in higher employability and lower empowerment of workers in modern market economies. Finally, we present conditions on the self‐interest of current shareholders to empower workers as a way to stimulate their investment in firm‐specific human capital.     

Environmental Policy Instruments: Technology Adoption Incentives with Imperfect Compliance

We study the incentives to adopt advanced abatement technologies in the presence of imperfect compliance. Interestingly, incentives under emission taxes and pollution abatement subsidies are the same that in the perfect compliance scenario. However, under emission standards imperfect compliance can increase firms’ incentives to invest, whereas under an emission permit mechanism investment incentives decrease only if widespread non-compliance induces a reduction in the permit price. Our results are valid for fairly general characteristics of the monitoring and enforcement strategies commonly found in both, theoretical and empirical applications.     

Market Structure And The Adoption Of Innovations: The Case Of The Spanish Banking Sector ‡

This paper is an empirical study of the determinants of adoption time for the teleprocess terminal by Spanish commercial and savings banks. The explanatory variables include the characteristics of the adopting firms, size, and in the case of the savings banks, the structure of the market and concentration. The results indicate that the speed of adoption is maximized at intermediate levels of size and market concentration, confirming one theoretical prediction of models of diffusion: namely, that adoption time is minimized at intermediate levels of market concentration.     

Measures of risk associated to regulations compliance: a laboratory experiment on the use of common-pool resources

The present research examined the influence of different risk perspectives by the use of four different target persons (who could be affected: abstract person, self, specific person, and specific others) and of four different questionnaire answer formats (rating, open percentage, open, and closed frequency) on risk assessments. It was assumed that subjects use two different systems in terms of probabilistic reasoning: a distributional approach for abstract targets leading to higher risk estimates and a singular approach for specific targets leading to lower risk assessments. According to unrealistic optimism (UO) research (showing higher risk assessments for an abstract person than for self), the assumption was that risk assessments for a specific (named) target lead to lower risk assessments compared to an abstract target. Further, common quantitative answer formats for assessing risk were compared to explore differences in risk estimates. The hypotheses were tested using data of a sample of 512 students from a Bavarian university. The frequently confirmed finding of UO could be replicated with both rating scale and open frequency scale, which appeared to be more sensitive compared to the other used scales. However, UO disappeared when the comparison target was specific. Further, risk assessments for an abstract target were highest within every answer format and lowest for specific targets. Furthermore, results revealed that the type of answer format has a moderating effect on the extent of the influence of risk perspective on risk assessments. Overall, this study gives evidence that both the chosen scale and the risk perspective strongly influence risk assessments. Results aim to contribute to the research fields of quantitative assessment of perceived risk. They suggest that probabilistic reasoning in regard to risk not only underlies motivational or cognitive ego-defensive mechanisms but is rather presumably caused by the use of different systems of inferential strategies.     

Estudio de los factores de compra de productos retro y segmentación del mercado potencial retro

This paper aims to analyze the behavior of potential retro products buyers. A bibliographical review has allowed defining the motives to buy this type of products. However, it should be emphasized that there is scarcely any quantitative information on the reasons to purchase and the segmentation of the potential retro product market. Using the data collected by means of a survey, a factor analysis and a cluster analysis have been performed. As a result, there are three factors of retro product purchase: characteristics of product, present differentiation feelings and past feelings. Furthermore, the existence of two differentiated segments has been detected: emotive consumer and commercial consumer.     

Trend breaks in the research and development process

This work examines the behaviour of the input and output measures of the R&D process in the United States, Germany, France and the United Kingdom, in the second half of the 20th century. The researcher and idea stock series can be construed as stationary fluctuations around a trend function, with a main breakpoint at the end of the 1960s. All the countries exhibit slower growth after their last breaks that during the decades preceding its first breaks. In this connection, the United States and Germany appear to represent the end points in the range of incidence.     

Causes of world trade growth in agricultural and food products, 1951–2000: a demand function approach

The objective of the present study is to analyse the causes of the growth of international agricultural and food trade in volume terms from 1951 to 2000. The results suggest that income growth has been the principal reason for this expansion, while exchange rate stability and the real price of agricultural products played only a minor role. Multilateral trade liberalization and trade costs, given their long-term stability, are not elements that could have stimulated their growth. Finally, the intensive liberalization of trade which took place in various economic regions, especially in Europe, became a key factor in promoting agricultural trade among the countries participating in regional trade agreements. The study results also indicate that the determinants of trade growth for these goods were different to those for other goods and other periods.     

Common dynamics of nonenergy commodity prices and their relation to uncertainty

The purpose of this article is to improve the empirical evidence on commodity prices in various dimensions. First, we attempt to identify the extent of comovements in 44 monthly nonenergy commodity price series in order to ascertain whether the increase in comovement is a recent term phenomenon. Second, we attempt to determine the role of uncertainty in determining comovements among nonenergy prices in the short run. We diagnose the overall comovement using a dynamic factor model estimated by principal components. A factor-augmented vector autoregressive approach is used to assess the relationship of fundamentals, financial and uncertainty variables with the comovement in commodity prices. We find a greater synchronization among raw materials since December 2003. Since that date, uncertainty has played an important role in determining short-run fluctuations in nonenergy raw material prices.
