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.     

Innovations in Retail Business Models

A retail business model articulates how a retailer creates value for its customers and appropriates value from the markets. Innovations in business models are increasingly critical for building sustainable advantage in a marketplace defined by unrelenting change, escalating customer expectations, and intense competition. Drawing from extant strategy and retailing research, we propose that innovations in retail business models are best viewed as changes in three design components: (1) the way in which the activities are organized, (2) the type of activities that are executed, and (3) the level of participation of the actors engaged in performing those activities. We propose six major ways in which retailers could innovate their business models to enhance value creation and appropriation beyond the levels afforded by traditional approaches to retailing. We also describe the drivers of business model innovations, the potential consequences of such innovations, and numerous examples from retail practice that highlight our concepts and arguments. In doing so, we provide a starting point for academic research in a domain that is deficient in theoretical and empirical research, and offer retailing managers a framework to guide retail business model innovations for sustainable competitive advantage.     

The Romanian researchers＇ profile and career in the knowledge based economy

This study examines the international profile and career of 157 Romanian researchers. The majority considers the insufficient funding of research in Romania as playing a major role in their decision to work in the knowledge based economy. In addition, the survey reveals several other factors which motivate the emigration of Romanian scientists. While abroad, the majority kept in touch with their former university/research institute, colleagues and/or the Romanian scientific community, in general. More than half of the respondents prefer to work outside Romania, after completing their current professional projects.
