On the evolution of institutional comparative advantages

This article investigates how comparative advantages have changed in the last 30 years. Using export data for 100 countries over the period 1976-2004, it provides evidence that comparative advantages are not static, but change over time. Focussing on three different sources of institutional comparative advantage, it shows that they display different trends over time. Additionally, it shows that these effects are generally stronger for OECD countries.     

FDI spillovers in new EU member states

Using an unbalanced panel of firm‐level data in Bulgaria, Poland and Romania, we examine the impact of foreign firms on domestic firms’ productivity. In particular, we try to answer the following research questions: (1) Are there any spillover effects of foreign direct investments (FDI), and if so, are they positive or negative? (2) Are spillover effects more likely to occur within or across sectors? (3) Are the existence, the direction and the magnitude of spillovers conditioned by sector and firm‐specific characteristics? Our findings show that FDI spillovers exist both within and across sectors. The former arise when foreign firms operate in labour‐intensive sectors, while the latter occur when foreign firms operate in high‐tech sectors. Moreover, we find that domestic firm size conditions the exploitation of FDI spillovers even after controlling for absorptive capacity. We also detect a great deal of heterogeneity across countries consistent with the technology gap hypothesis.     

Pluralism at Risk? Heterodox Economic Approaches and the Evaluation of Economic Research in Italy

We analyze Italy's recent research evaluation exercise (VTR) as a salient example in discussing some internationally relevant issues emerging from the evaluation of research in economics. We claim that evaluation and its criteria, together with its linkage to research institutions' financing, are likely to affect the direction of research in a problematic way. As the Italian case documents, it is specifically economists who adopt unorthodox paradigms or pursue less diffused topics of research that should be concerned about research evaluation and its criteria. After outlining the recent practice of economic research in Italy and highlighting the relevant scope for pluralism that traditionally characterizes it, we analyze the publications submitted for evaluation to the VTR. By comparing these publications to all the entries in the EconLit database authored by economists located in Italy, we find a risk that the adopted ranking criteria may lead to disregarding historical methods in favor of quantitative and econometric methods, and heterodox schools in favor of mainstream approaches. Finally, by summarizing the current debate in Italy, we claim that evaluation should not be refused by heterodox economists, but rather that a reflection on the criteria of evaluation should be put forward at an international level in order to establish fair competition among research paradigms, thus, preserving pluralism in the discipline.     

Was there a Nasdaq bubble in the late 1990s?

Not necessarily: a firm's fundamental value increases with uncertainty about average future profitability, and this uncertainty was unusually high in the late 1990s. After calibrating a stock valuation model that takes this uncertainty into account, we compute the level of uncertainty that is needed to match the observed Nasdaq valuations at their peak. The uncertainty we obtain seems plausible because it matches not only the high level but also the high volatility of Nasdaq stock prices. In general, we argue that the level and volatility of stock prices are positively linked through firm-specific uncertainty about average future profitability.     

Stock Valuation and Learning about Profitability

We develop a simple approach to valuing stocks in the presence of learning about average profitability. The market‐to‐book ratio (M/B) increases with uncertainty about average profitability, especially for firms that pay no dividends. M/B is predicted to decline over a firm's lifetime due to learning, with steeper decline when the firm is young. These predictions are confirmed empirically. Data also support the predictions that younger stocks and stocks that pay no dividends have more volatile returns. Firm profitability has become more volatile recently, helping explain the puzzling increase in average idiosyncratic return volatility observed over the past few decades.     

Habit formation,the cross section of stock returns and the cash-flow risk puzzle

Non-linear external habit persistence models, which feature prominently in the recent “equity premium” asset pricing and macroeconomics literature, generate counterfactual predictions in the cross-section of stock returns. In particular, we show that in the absence of cross-sectional heterogeneity in firms’ cash-flow risk, these models produce a “growth premium,” that is, stocks with high price-to-fundamental ratios command a higher premium than stocks with low price-to-fundamental ratios. This implication is at odds with the well-established empirical observation of a “value premium” in the cross-section of stock returns. Substantial heterogeneity in firms’ cash-flow risk yields both a value premium as well as most of the stylized facts about the cross-section of stock returns, but it generates a “cash-flow risk puzzle”: Quantitatively, value stocks have to have “too much” cash-flow risk compared to the data to generate empirically plausible value premiums.     

Nursing is the room rate

Shrinking dollars increase the need for health care stakeholders to clearly understand nursing's worth. For nursing to assure an adequate investment in nurses, it needs to articulate its value drivers. Nursing revenue offers a data source that reflects stakeholder choices and patient needs. The daily nursing billing supports hospital payment and provides cost data, important for hospital financial decision making. This revenue is a tangible asset reflecting nursing value and can be used to justify an investment in the profession. Nursing leadership can use this daily nursing charge data to monitor and measure the impact of efficiencies related to patient care.     

On the determinants of capital flight from Russia

The paper addresses the problem of defining and assessing the scale of capital flight from Russia and of briefly reviewing the channels through which capital, both of legal and illegal origin, illegally leaves Russia. It then highlights the determinants of Russian capital flight, as the traditional view of a reaction to divergences among real domestic and foreign returns and to economic and political risks proves inadequate. More important factors are linked to specific features of the transition process under way, that is macroeconomic instability and variability of government policies, weak protection of property rights and savings, a fragile banking system limiting access to investment finance, high and unevenly enforced taxes, a large share of unofficial activities, and considerable levels of corruption.     

Choosing price or quantity? The role of delegation and network externalities

We consider a differentiated duopoly and endogenise the firm choice of the strategy variable (price or quantity) to play on the product market in the presence of network externalities. We model this choice by assuming both competition between entrepreneurial (owner-managed) firms and competition between managerial firms in which market decisions are delegated from owners to revenue-concerned managers. While network externalities are shown not to alter the symmetric equilibrium quantity choice arising in the no-delegation case, sufficiently strong network effects allow us to eliminate the multiplicity of equilibria under delegation and lead to a unique equilibrium in which both firms choose price.
