Patent pools,vertical integration,and downstream competition

Patent pools are commonly used to license technologies to manufacturers. Whereas previous studies focused on manufacturers active in independent markets, we analyze pools licensing to competing manufacturers, allowing for multiple licensors and nonlinear tariffs. We find that the impact of pools on welfare depends on the industry structure: whereas they are procompetitive when no manufacturer is integrated with a licensor, the presence of vertically integrated manufacturers triggers a novel trade‐off between horizontal and vertical price coordination. Specifically, pools are anticompetitive if the share of integrated firms is large, procompetitive otherwise. We then formulate information‐free policies to screen anticompetitive pools.     

The risk-shifting effect and the value of a warrant

The exercise of a warrant leads to the well-known dilution phenomenon, the effects of which have been extensively studied over the last four decades. In contrast, the existing literature has paid inadequate attention to the volatility spillover between stockholders and warrant holders. This ‘risk-shifting effect’ has significant implications for warrant pricing, since any formula that assumes a constant volatility of stock returns produces a bias. In this paper we show that a CEV process with a specific elasticity parameter properly models the stochastic volatility of stock returns for a firm with warrants outstanding. In addition, we propose an approximate analytical formula, exclusively based on observable market variables, that is able to absorb the risk-shifting bias.     

Bankruptcy law and corporate investment decisions

Major European countries have recently adopted bankruptcy codes that strengthen entrepreneurs’ power to renegotiate outstanding liabilities. Renegotiation in bankruptcy allows lenders to increase recovery rates, however it also weakens the contract’s ability to solve the moral hazard problem embedded in the production project. Hinging on this trade-off, I show in which circumstances a soft bankruptcy law that resembles Chapter 11 in the balance of lenders’ and entrepreneur’s rights encourages the choice of investments that privilege the achievement of long-term results. However, I also show that, in contrast to the common wisdom, soft bankruptcy can lead to the choice of investments that are biased towards the achievement of short-term outcomes.     

Paying not to sell

In this paper we show that, in the presence of buyer and seller power, a monopolist can enter into a costly contractual relationship with a low-quality supplier with the sole intention of improving its bargaining position relative to a high-quality supplier, without ever selling the good produced by that firm.     

Policy impact assessment in developing countries using Social Accounting Matrices: The Kenya SAM 2014

This paper describes the structure and estimation of a Social Accounting Matrix (SAM) of Kenya for the year 2014. Among its specificities, this SAM includes a very high disaggregation of the agri‐food sector and accounts for the double role of households as producers and consumers. Accounting for these characteristics is crucial to provide robust socioeconomic analysis in the context of developing countries. Indeed, this type of database is valuable to perform ex‐ante evaluations of economic policies with various economic models and techniques. In this paper, we present an application with a linear multiplier analysis (backward linkages and value chain decomposition). The results show the capacity of the primary sector in Kenya to generate value added and employment, with this growth distributed more intensely in rural households whose main livelihood is semi‐subsistence agriculture.     

Informal adult care and caregivers' employment in Europe

I discuss instrumental variable estimates of the effect of providing unpaid adult care on the caregivers' probability of being employed, using eight waves of the European Community Household Panel. I focus on men aged 40–64 and women aged 40–59 from thirteen Member States, aggregated in two groups of Northern-Central and Southern countries. Previous papers with European data found that IV estimates are more negative than estimates assuming exogeneity of caregiving. I show that this difference is not robust once account is taken of time-invariant unobserved heterogeneity. Indeed, instruments turn out not to be needed, and the estimated effect is negative, but small in both groups of countries.     

Firm size, business experience and export intensity in SMEs: A longitudinal approach to complex relationships

The objective of the paper is to test the effect of firm size and business experience on export performance. In fact, despite a growing number of empirical studies, the question of the relationship between these variables is not clearly established. This research aims at contributing to a better understanding of these complex relationships with a special focus on small and medium-sized enterprises (SMEs). The authors develop a general model and test it using a sample of Italian manufacturing firms that spans the 1997–2001 period. Combining a time-series with a cross-sectional analysis, they use an econometric model in order to test the relationships. Their findings provide a strong support for both relationships. The results show that it is not business experience per se which is important but that it is the relative change in experience that truly impacts upon export performance. The model also reveals that industry effects are relevant.     

Strategic accessibility competition

We analyze the effect of competition in market-accessibility enhancement among quality-differentiated firms. Firms are located in regions with different ex-ante transport costs to reach the final market. We characterize the equilibrium of the two-stage game in which firms first invest to improve market accessibility and then compete in prices. Efforts in accessibility improvement crucially depend on the interplay between the willingness to pay for the quality premium of the median consumer and the ex-ante difference in accessibility between regions. From the social standpoint, also the accessibility investment depends on such a comparison. Finally, we endogenize quality choice and check the robustness of the result to some natural modifications of our assumptions.     

The Phasing of Fiscal Adjustments: What Works in Emerging Market Economies?

This paper investigates the political and economic determinants of successful fiscal adjustment in 25 emerging market economies from 1980 to 2001. The results show that large and back‐loaded fiscal adjustments have the highest likelihood of success. Fiscal consolidations based on expenditure cuts increase the probability of approaching and achieving fiscal sustainability but are insufficient to maintain it unless accompanied by revenue reforms. Adjustment episodes launched in countries where governments enjoy a parliamentary majority and do not face imminent elections, are found to be more successful. Fiscal consolidations undertaken under IMF‐supported programs also have a higher probability of success.
