DOES THE EFFECT OF PUBLIC SUPPORT FOR R&D DEPEND ON THE DEGREE OF APPROPRIABILITY?*

We explore the interaction between public support for R&D and appropriability using a dataset constructed from the Spanish Community Innovation Survey, for the period 2000–2005. We find that public support policy is less able to stimulate privately financed internal R&D in firms where appropriability mechanisms are more effective. On average, the effect of public support for R&D is three times larger for those firms reporting a level of appropriability below the median vis‐à‐vis those firms for which appropriability is above the median level. Furthermore, for supported firms with the highest degree of appropriability, crowding out cannot be ruled out.     

The Duration of Union Membership in Italy: A Research Note

Thanks to direct access to union databases, this note can answer two new questions in industrial relations: how long union membership lasts and what are the determinants of its duration within an open‐shop context. This also allows for conceptualizing union membership as a much more dynamic phenomenon than in previous studies, where it was considered a static condition whose causes or effects were to be investigated. Regression analysis applied to a sample of 29,035 Italian workers highlights that union membership duration is a positive but declining function of age. Furthermore, women, flexible workers, foreign ones, and those working in cities tend to show less attachment to union membership than the other workers.     

The Disposition Effect and Underreaction to News

This paper tests whether the “disposition effect,” that is the tendency of investors to ride losses and realize gains, induces “underreaction” to news, leading to return predictability. I use data on mutual fund holdings to construct a new measure of reference purchasing prices for individual stocks, and I show that post‐announcement price drift is most severe whenever capital gains and the news event have the same sign. The magnitude of the drift depends on the capital gains (losses) experienced by the stock holders on the event date. An event‐driven strategy based on this effect yields monthly alphas of over 200 basis points.     

The embodiment of class,gender and age through leisure: a realist analysis of long distance running

Leisure activities claiming to promote health and fitness have been an increasing feature of contemporary society. The impact of such activities on social inequality is an important area of study for both theoretical and policy reasons. This paper adopts an embodied approach to explore the development of long‐distance running and the gendered, aged and classed nature of it. It is based upon part of a study which involved analysing a running magazine which was first entitled Jogging Magazine, quickly became Running and is now known as Runner's World, and ten interviews with runners. The paper illustrates connections between the knowledges, practices, organization and values promoted through running (from 1979–1998) and the growing popularity of a particular bodily type and style. The popularity of the slender muscular body has developed with the growth of leisure‐sports like running. It has become the ideal for men and women of all ages, but has been particularly related to the middle‐classes. Participation is thought to bring both health and aesthetic benefits for individuals. From the realist perspective adopted, the necessary mechanisms of running culture and the forms of embodiment promoted can be viewed as important in constituting class, gender and age processes. I suggest that viewing the emergent powers of sports like running utilising embodied approaches is important because they raise issues around the promotion of leisure activities that are viewed as unproblematically ‘healthy’. In the case of running it is found that it promotes an embodiment of middle‐classness that naturalizes gender and age inequalities whilst also individualising responsibility for them.     

The Home Bias and the Credit Crunch: A Regional Perspective

Using detailed data on loan applications and decisions for a large sample of manufacturing firms in Italy during the recent financial crisis, we find that the credit crunch has been harsher in provinces with a large share of branches owned by distantly managed banks. Inconsistent with a flight to quality we do not find evidence that economically weaker firms suffered more during the crisis. In contrast, we find that financially healthier firms were affected more in functionally distant credit markets than in markets populated by less distant banks, consistent with a home bias on the part of nationwide banks.     

When Uncertainty Blows in the Orchard: Comovement and Equilibrium Volatility Risk Premia

We provide novel evidence for an equilibrium link between investors' disagreement, the market price of volatility and correlation, and the differential pricing of index and individual equity options. We show that belief disagreement is positively related to (i) the wedge between index and individual volatility risk premia, (ii) the different slope of the smile of index and individual options, and (iii) the correlation risk premium. Priced disagreement risk also explains returns of option volatility and correlation trading strategies in a way that is robust to the inclusion of other risk factors and different market conditions.     

House Price Booms,Current Account Deficits,and Low Interest Rates

Domestic factors, such as credit and preference shocks, can explain the negative correlation between house prices and the current account in the U.S. and several other countries before the recent crisis. These shocks, however, cannot account for the fall of world real interest rates observed in the data. Expansionary monetary policy shocks in the U.S., coupled with exchange rate pegs to the dollar in emerging economies, are crucial to understanding the evolution of the real interest rate. Yet, monetary policy factors play virtually no role for house prices and the current account.     

Sectoral Money Demand and the Great Disinflation in the United States

Estimates of the welfare costs of inflation based on Bailey (1956) are typically computed using aggregate money demand models. Yet, the behavior of money demand may vary across sectors. Thus, the impact on welfare of inflation regime shifts may differ between households and firms. We specifically investigate the sectoral welfare implications of the shift from the Great Inflation to the present regime of low and stable inflation. For this purpose, we estimate different functional specifications of money demand for U.S. households and nonfinancial firms using flow‐of‐fund data covering four decades. We find that the benefits were significant for both sectors.     

The Advantage of Flexible Targeting Rules

This paper investigates the consequences of debt stabilization for inflation targeting. If the fiscal authority holds constant the real value of debt at maturity under strict inflation targeting, the equilibrium dynamics are indeterminate for a wide range of parameters and steady‐state fiscal stances. “Flexible” targeting rules that include a concern for stabilization of the output gap can restore determinacy of the equilibrium. Flexible inflation targeting appears to be more robust than flexible debt targeting to alternative parameterizations. The fiscal authority can prevent indeterminacy under strict targeting rules by committing to hold constant debt net of interest rate spending.     

The Intraday Price of Money: Evidence from the e‐MID Interbank Market

We provide empirical evidence, based on tick‐by‐tick data for the e‐MID euro area interbank market covering 2003 and 2004, that the overnight interest rate shows a clear downward pattern throughout the operating day. Thus, a positive hourly interest rate (half basis point) implicitly emerges from the intraday term structure of the overnight rate. Such a pattern was not detected in the mid‐1990s: we explain this evolution as an outcome of the recent trend toward real‐time settlement. The estimated intraday interest rate is lower than in the United States: this is due to the different cost of central bank daylight credit.
