The use of short role-plays for an ethics intervention in university auditing courses

This paper reports how short 10-minute role-plays can be used as an effective tool for ethics education within university auditing classes. A mixed method approach elicited student perceptions of role-plays in developing ethical awareness. While many students self-reported difficulty in recognising and dealing with the ethical dilemmas appropriately, most agreed role-plays helped them to prepare for dealing with these issues in the workplace. This was especially the case for students with English as an additional language. Students reported the role-play ethical dilemmas raised their awareness of the need to protect their professional independence. Students commented that they had a better understanding of the importance of the professional code of conduct and the code of ethics. Role-plays are a simple experiential learning approach that helps students to recognise ethical dilemmas, explore strategies to deal with such dilemmas in a safe environment, and practice listening and questioning skills to obtain information. Short role-plays can offer critical thinking opportunities that are more relevant to the student’s personal experience than case studies of historical ethical breaches.     

Inflation targeting regimes

This paper divides the monetary frameworks of countries that use an inflation target to define their monetary framework into three different regimes: (i) full-fledged inflation targeting, (ii) implicit price stability anchor, and (iii) inflation targeting lite. The regimes are differentiated by the clarity and credibility of the commitment to the inflation target. The revealed preference for different regimes is related empirically to cross-country structural differences in economic and financial development. Policy implications of moving from one regime to another are drawn, especially for emerging market countries aiming at full-fledged inflation targeting.     

Do entrepreneurs really earn less?

Based on large representative German household survey data, we compare incomes of the self-employed with those of paid employees. We find that the entrepreneurial income gap is largest for those holding a tertiary degree, but in two directions: positive for employers (self-employed with further employees) and negative for solo entrepreneurs. Entrepreneurs holding a tertiary degree also face the greatest income variation. However, some solo self-employed earn more than their employed counterparts, in particular those with a university entrance degree as the highest level of education.     

Discussing the political survival of Romanian ministers since 1989—Do economic conditions matter?

Political longevity in young democracies has attracted the attention of scholars and practitioners alike due to several particular characteristics of such democracies, such as a low level of trust, a low level of credibility, corruption, economic difficulties, a less well‐established rule of law and an increased bureaucracy. In such a context, we studied the tenure duration of Romanian ministers since 1989, as well as their accumulated political longevity in ministerial offices. Using proportional hazards regression, we observed some peculiarities in the young Romanian democracy in comparison with more established regimes. We observed that left‐wing majorities tend to increase the probability of seat changes and thus diminish tenure longevity. We also observed that good economic conditions may lead to the substitution of certain types of ministries, while higher inflation rates tend to shorten tenure longevity for Romanian ministers. Moreover, our estimations support the finding that Romanian ministers tend to have shorter tenures as the number of past ministerial functions increases and that the burden of simultaneously managing various ministries significantly contributes to the shorter political longevity of a given minister. Finally, recent ministers have had longer tenures than those in the first years after the fall of communism in Eastern Europe in 1989.     

Do Women Have Different Labor Supply Behaviors? Evidence Based on Educational Groups in Uruguay

This study uses Uruguay’s historical fluctuation in real wages to set up a natural experiment to measure the relation between women’s labor supply and wages. Using data from the Continuous Household Surveys of the Uruguayan National Statistics Institute, for 1986–2010, it aims to identify and explain heterogeneity in the labor supply behavior of women with different educational backgrounds. It finds that all women groups seek to optimize their remunerated work allocation throughout their life cycle, although women’s labor behaviors vary depending on educational levels. The rising trend of women’s labor force participation is expected to continue; its implications at the intensive margin are ambiguous and depend on how women conciliate paid work with household responsibilities – especially women with less education. These results could inform present debates about designing public policies to facilitate women’s entry into the labor market and cater to their different wage profiles and household care demands.     

Competing with loyalty: How to design successful customer loyalty reward programs

For industries with low switching costs, customer loyalty programs (LPs) have potential to drive differentiation and sustain a competitive advantage. However, incentives provided through LPs also have a potential to escalate into costly price wars. In this article, we discuss how to design successful customer loyalty reward programs that bring value to participants and that cannot be emulated by competitors easily. We focus on three distinct aspects of improvement: personalization, reward types, and additional services. Through personalization, companies can leverage the knowledge they already have on their customers to tailor offers that they find relevant and appealing. For the reward structure, we argue in favor of a certain degree of opacity. We also encourage loyalty programs to consider giveaways that are unique and difficult to imitate and to use all the information they have available to provide rewards that fit with each customers’ idiosyncratic situation or preference. Finally, competitive LPs should look beyond offers and rewards. In addition to purchases, LPs can reward participants for other desirable behaviors; they can also provide additional services that impose minimal costs on firms, but bring value to customers.     

Information transfer and conference calls

A long-standing literature documents intra-industry capital market co-movements around earnings releases, yet the dynamics of these information transfers remain largely unexplored. We provide evidence on both the sources and channels of information transfers by separating two distinct events within the reporting window using intra-day data and by exploring potential mechanisms of information flows. We document that the co-movement of absolute and signed stock returns over the conference call windows of announcing firms and their industry peers are statistically and economically larger than the co-movement over the corresponding earnings announcement windows. Turning to mechanisms, we find that shared analyst coverage, coverage by analysts providing industry recommendations, shared institutional ownership, and joint financial media mentions are each individually and incrementally associated with higher rate of information transfer over both the earnings announcement and conference call windows. Textual analyses reveal that peer mentions and macroeconomic discussions both significantly contribute to conference call information transfers.     

What drives credit dollarization in transition economies?

This paper provides an in-depth analysis of the use of foreign currencies in the lending activities of banks in transition economies. The impact of bank and firm variables on credit dollarization is studied in an optimal portfolio allocation model and estimated using new aggregate data for 21 transition economies for the period 1990–2003. Empirical results provide evidence that credit dollarization is the combined outcome of domestic deposit dollarization and banks’ desire for currency-matched portfolios beyond regulatory requirements. The effects of international financial factors and natural hedges are less robust across alternative specifications. The paper further discusses the role of regulations in affecting the impact of these factors on credit dollarization and calls for more developed domestic forward foreign exchange markets.
