Scale Efficiency and Productivity Change

Thefirst objective of this paper is to develop a generic measureof scale efficiency for a multiple-input multiple-output firm,using basic principles of modern production theory. The secondobjective is to combine measures of technological change, technicalefficiency change, and scale efficiency change into an encompassing(primal) measure of productivity change. This measure and itsdecomposition is compared to a number of recent proposals inorder to shed light on what seems to have become a controversialissue. The paper proceeds by developing an encompassing dualmeasure of productivity change. This dual measure is then appliedto panel data of a set of Dutch firms, continuing the empiricalwork of Balk (1998). It turns out that extending the Malmquistproductivity index with factors measuring scale efficiency changeand input mix change leads to appreciably different outcomes.     

The Opportunity Cost of Negative Screening in Socially Responsible Investing

This paper investigates the impact of negative screening on the investment universe as well as on financial performance. We come up with a novel identification process and as such depart from mainstream socially responsible investing literature by concentrating on individual firms’ conduct and by studying a much wider range of issues. Firstly, we study the size and financial performance of fourteen potentially controversial issues: abortion, adult entertainment, alcohol, animal testing, contraceptives, controversial weapons, fur, gambling, genetic engineering, meat, nuclear power, pork, (embryonic) stem cells, and tobacco. We investigate an international sample of more than 1,600 stocks for more than twenty years. We then analyze the impact of applying negative screens to a market portfolio. Our findings suggest that the choice for negative screening strategies does matter for the size of the investment universe as well as for risk-adjusted return performance. Investing in controversial stocks in many cases results in additional risk-adjusted returns, whereas excluding them may reduce financial performance. These findings suggest that there are opportunity costs to negative screening.     

Cultural Values and International Differences in Business Ethics

We analyze ethical policies of firms in industrialized countries and try to find out whether culture is a factor that plays a significant role in explaining country differences. We look into the firm’s human rights policy, its governance of bribery and corruption, and the comprehensiveness, implementation and communication of its codes of ethics. We use a dataset on ethical policies of almost 2,700 firms in 24 countries. We find that there are significant differences among ethical policies of firms headquartered in different countries. When we associate these ethical policies with Hofstede’s cultural indicators, we find that individualism and uncertainty avoidance are positively associated with a firm’s ethical policies, whereas masculinity and power distance are negatively related to these policies.

The stocks at stake: Return and risk in socially responsible investment

We relate US portfolio returns, book-to-market values and excess stock returns to different dimensions of socially responsible performance. We find that socially responsible investing (SRI) impacts on stock returns by lowering the book-to-market ratio and not by generating positive alphas. Our result is consistent with the theoretical work suggesting that SRI is reflected in demand differences between SRI and non-SRI stock. It also explains why so few studies are able to establish a link between alpha’s and SRI.     

Do Retail Foreign Direct Investment Restrictions Affect Retail Channel Structure?

The purpose of this study is to contribute to the existing retail channel structure research by investigating the impact of retail foreign direct investment (FDI) restrictions on retail channel structure as well as the moderating impact of a country's level of economic development on this relationship. Using a panel data set of 79 countries over the period 1999–2012, we show that retail FDI restrictions can influence retail channel structure development and that the relationship between retail FDI restrictions and retail channel structure is moderated by a country's level of economic development.     

Testing uncovered interest rate parity using LIBOR

We test uncovered interest rate parity (UIP) using London InterBank Offered Rate (LIBOR) interest rates for a wide range of maturities. In contrast to other markets, LIBOR markets have minimal frictions. Whereas most previous studies reject UIP, we find that UIP holds for several short-term LIBOR maturities using block bootstrap panel unit root tests suggested by Palm et al. (2011) and cointegration techniques by Westerlund (2007). Furthermore, the estimation results suggest that the speed of adjustment to the long-run equilibrium marginally differs across the maturity of the underlying instrument, thus supporting the efficient market hypothesis.     

An empirical analysis of excess interbank liquidity: a case study of Pakistan

We investigate the drivers of excess interbank liquidity in Pakistan, using the Autoregressive Distributed Lag approach on weekly data for December 2005 to July 2011. We find that the financing of the government budget deficit by the central bank and nonbanks leads to persistence in excess liquidity. Moreover, we identify a structural shift in the interbank market in June 2008. Before June 2008, low credit demand was driving the excess liquidity holdings by banks. After June 2008, banks’ precautionary investments in risk-free securities drive excess liquidity holdings. Monetary policy is less effective if banks hold excess liquidity for precautionary reasons.     

中国的税制改革(下)

(接上期)四、扩大地方政府的财政自主权在中国,相当一部分公共服务都是由地方政府提供的。中国的地方政府分成以下四级:省、市、县/区、乡镇。这些地方政府负责提供如卫生、教育、退休金、失业保险和最低生活保障等重要的公共服务。除此之外,这些地方政府还要负责大部分的城市基础设施(例如交通和改善环境)投资(World Bank,2012)。地方政府的地方税税基非常有限,调整税率的权力几     

Online Music Consumption in Today’s Technological Context: Putting the Influence of Ethics in Perspective

Whereas in the past ‘free’ and ‘illegal’ were nearly synonymous in the music industry, consumers nowadays face a myriad of music platforms with widely different characteristics in terms of business model (advertising supported, fee based, etc.), delivery mode (streaming, downloading, etc.), and others. The current research examines music consumption preferences in this new context. In order to break with the outmoded free-illegal versus paid-legal dichotomy, the present research studies consumer preferences for a broader range of music platform attributes, including free versus paying business models, (il)legality of use, artist revenues, downloading versus streaming, and audio quality. Based on a literature review and a qualitative study with in-depth interviews (N = 92), an online conjoint survey (N = 764) quantifies online music preferences. Results show that consumers of all ages clearly and consistently prefer legal and ethical options if available, but favor different ways of making this economically viable. Youngsters and young adults are more open to advertising, while middle-aged adults are more often willing to pay for advertising-free platforms. Thus, in real-life choices, youngsters may appear to be less ethical and law abiding, but the driving force behind this is mainly economical. Finally, a market segmentation provides deeper insights into online music consumer preferences and leads to recommendations on how to define viable legal and ethical music offerings.
