Conditional tail-risk in cryptocurrency markets

In this paper we use $CoVaR$ to estimate the conditional tail-risk in the markets for bitcoin, ether, ripple and litecoin and find that these cryptocurrencies are highly exposed to tail-risk within cryptomarkets, while they are not exposed to tail-risk with respect to other global assets, like the U.S. equity market or gold. Although cryptocurrency returns are highly correlated one with the other, we find that idiosyncratic risk can be significantly reduced and that portfolios of cryptocurrencies offer better risk-adjusted and conditional returns than individual cryptocurrencies. These results indicate that portfolios of cryptocurrencies could offer attractive returns and hedging properties when included in investors’ portfolios. However, when we account for liquidity, the share of crypto assets in investors’ optimal portfolio is small.     

Matchmaking in organizational change: Does every employee value participatory leadership? An empirical study

Although leadership is generally considered an important lever to increase commitment during organizational change, empirical research has yet to unravel many of the underlying mechanisms. In this paper, we propose that the impact of participative leadership on affective commitment to change will be contingent on employees’ orientation toward leadership. In our empirical study in two police organizations, we find evidence that followers’ orientation toward leadership is a useful interacting variable. Participative leadership lowers affective commitment to change for individuals with high dominance orientation. In contrast, participative leadership increases affective commitment to change for employees with high development orientation toward leadership. Implications for theory and practice are discussed.     

Advertising,industry innovation,and entry deterrence

With the advent of the Internet and social media platforms, advertising has become cheaper and more effective in reaching consumers. This paper studies the effect of better informative advertising on innovation and industry growth. This paper finds that improvements in informative advertising can lead to costly entry deterrence. Because advertising and innovation are complementary, better advertising raises the threats of entry. When innovation spillover is present in an industry, an incumbent firm has incentives to strategically lower its own innovation to deter entry. As a result, better advertising in innovation-intensive industries can have negative consequences on industry growth and consumer welfare. This paper also investigate the role of innovation spillover on entry deterrence.     

Trade and dietary diversity in Eastern Europe and Central Asia

In public and academic debates, the linkages between agricultural markets and nutrition across the world are vividly discussed. This paper contributes to the ongoing debate by analyzing the relationship between greater openness to trade and dietary diversity. It focuses on the post-communist countries of Eastern Europe and Central Asia where trade reforms triggered growth in trade flows and foreign direct investment, which in turn affected food systems in these countries. This shift provides a natural experiment for studying the effects of trade openness on agricultural markets and consumer behaviour. Reduction in trade barriers, for instance in the context of the accession to the WTO and the EU, and the gradual integration with world markets after 1991 had implications for diets through changes in production, prices and incomes. We utilize country-level panel data for 26 post-communist countries in the period 1996–2013 to assess the effects of trade costs, agricultural trade openness and incomes on dietary diversity measured by the Shannon entropy index. The results from fixed effects and instrumental variables estimation are consistent with previous findings that income growth affects dietary diversity positively. They also provide novel evidence that trade barriers reduce variety of products available in domestic markets, in particular fruits and vegetables.     

Is DNA fingerprinting the gold standard for estimation of adoption and impacts of improved lentil varieties?

In the early 1980s, disease susceptibility in short-season lentil landraces began to limit productivity in areas where relay cropping took place in Bangladesh. Since then, several improved high-yielding lentil varieties, which are resistant to rust and blight and suitable in the relay cropping system, have been released jointly by national and international research centers. This study used three methods, namely a panel of experts, a survey of 1000 households where the respondents named the variety they used, and DNA fingerprinting of seed samples collected from all lentil plots cultivated by survey households to estimate adoption. Double hurdle and instrumental variables regression methods were applied to the household survey and DNA fingerprinting data to identify determinants of adoption and measure their impacts. Of particular interest was whether estimates of adoption, determinants of adoption and impacts varied by method of variety identification. Results showed that the expert panel overestimated the adoption of more recent varieties while about 89% of the farmer-reported varieties were accurate, as verified by DNA fingerprinting. DNA fingerprinting appears to have little advantage for estimating the level of adoption in this case, where few varieties of lentils are found, local variety names do not exist, and most seed is obtained through a formal system. However, even under these conditions, determinants of adoption vary by identification method, and use of farmer-reported information on the variety can lead to erroneous conclusions about determinants of adoption. Because recent breeding efforts have focused on taste and cooking considerations, yield impacts were not significantly different from zero.     

Optimal social security tax with myopic agents

Myopic agents lack the foresight to save for their own old age. It is generally believed that correcting myopia is a rationale for a pay-as-you-go (PAYG) pension system. This view has been supported by existing literature showing that the optimal PAYG social security tax should increase when people are more myopic. In this paper we obtain new results opposed to the traditional view. By establishing a very standard general equilibrium OLG model with myopic agents and endogenized marginal product of capital, we show that the optimal social security tax should be lower when people are more myopic. Our numerical analysis also shows that the welfare cost of the social security tax increases with people's degree of myopia. These results suggest that correcting myopia is not a clear rationale for the PAYG social security.     

Does partnering with the World Bank shield investors from political risks in less developed countries?

This study explores whether partnering with the World Bank’s International Finance Corporation (IFC) protects foreign investors from aggressive actions by host countries’ governments. Building on the obsolescing bargaining model, we theorize that host states fear that hostile actions towards IFC-supported investments will damage their relationships with the World Bank. Within this context IFC support deters host government aggression towards investments. We assess our argument using country-level panel data as well as interviews with a sample of high-level managers. Findings suggest that IFC-support helps to reduce host state aggression against investing firms.     

Analyzing the influence of firm-wide integrated marketing communication on market performance in the hospitality industry

Over the last decade, scholars have recently emphasized the need for tourism marketers to orchestrate the wide range communication activities and forms via the adoption of Integrated Marketing Communication (IMC). However, prior research has almost neglected the role of IMC in hospitality management. This paper adopts a broad organizational approach conceiving IMC as a concept that involves the whole organizational entity and aims to analyze the effects of IMC on market performance, in terms of superior sales and financial results, greater brand advantage and customer-related outcomes for those businesses providing lodging services. To pursue this research purpose, a survey has been conducted among corporate-level senior managers of lodging businesses operating in Spain. The findings provided further and more compelling empirical proof of the positive influence of IMC on market performance, responding to the call for more rigorous empirical research to demonstrate the beneficial effects of firm-wide IMC on market performance.
