Stable Assignment of Public Facilities under Congestion

We study the problem of locating multiple public facilities when each member of society has to be assigned to exactly one of these facilities. Individuals' preferences are assumed to be single‐peaked over the interval of possible locations and negatively affected by congestion. We characterize strategy‐proof, efficient, and stable allocation rules when agents have to be partitioned between two groups of users and discuss the normative content of the stability property. Finally we prove that when more than two groups have to be formed, even with common information on the distribution of the peaks, there is no strategy‐proof, efficient, and stable allocation rule.     

The Valuation of Complex Derivatives by Major Investment Firms: Empirical Evidence

This article examines the auction of a portfolio of collateralized mortgage obligations (CMOs) to major broker dealers and institutional investors. The unique data set allows us to analyze a number of important empirical questions related to the valuation of CMOs by the bidders and the elasticity of demand for the securities. The results reveal that the valuations differ substantially implying a significant elasticity of demand.     

Simulated Non-Parametric Estimation of Dynamic Models

This paper introduces a new class of parameter estimators for dynamic models, called simulated non-parametric estimators (SNEs). The SNE minimizes appropriate distances between non-parametric conditional (or joint) densities estimated from sample data and non-parametric conditional (or joint) densities estimated from data simulated out of the model of interest. Sample data and model-simulated data are smoothed with the same kernel, which considerably simplifies bandwidth selection for the purpose of implementing the estimator. Furthermore, the SNE displays the same asymptotic efficiency properties as the maximum-likelihood estimator as soon as the model is Markov in the observable variables. The methods introduced in this paper are fairly simple to implement, and possess finite sample properties that are well approximated by the asymptotic theory. We illustrate these features within typical estimation problems that arise in financial economics.     

MIGRATION, UNEMPLOYMENT, AND WAGES: THE CASE OF THE CALIFORNIA SAN JOAQUIN VALLEY

The California San Joaquin Valley labor market appears to be at odds with basic economic principles in the sense that despite higher unemployment rates and lower wages, it has continually attracted an influx of in‐migrants, domestic and international. By examining county‐level data for the last two decades, the analysis in this paper is built around two main questions. First, in what proportion does local employment growth reduce local unemployment, increase labor force participation and attract outsiders who will likely take the newly created jobs? Second, to what extent regional migration rates respond to regional relative wages and unemployment differentials? Both questions aim to gain a better understanding of the San Joanquin Valley labor market and the migrants’ decisions to move there, which might shed light in the design and implementation of development policies aimed at reducing unemployment. Results provide evidence that market forces alone are insufficient to correct regional unemployment disparities. Three main findings are offered. First, in‐migrants workers fill most of the newly created jobs. Second, migration seems unresponsive to the unemployment level but responsive to changes in farm income. Third, migration is sensitive to government‐based benefits, property crime rates and housing prices. (JEL R11, R23, R58)     

New Keynesian Macroeconomics and the Term Structure

This article complements the structural New Keynesian macro framework with a no-arbitrage affine term structure model. Whereas our methodology is general, we focus on an extended macro model with unobservable processes for the inflation target and the natural rate of output that are filtered from macro and term structure data. We find that term structure information helps generate large and significant parameters governing the monetary policy transmission mechanism. Our model also delivers strong contemporaneous responses of the entire term structure to various macroeconomic shocks. The inflation target shock dominates the variation in the "level factor" whereas monetary policy shocks dominate the variation in the "slope and curvature factors."     

Inward investment and endogenous development. The convergence of the strategies of large firms and territories?

Inward investment is often understood as an inadequate instrument for self-sustained growth and as being responsible for the insufficient development of peripheral areas. Globalization and increasing competition within the markets, however, changed the firms' and regions' adjustment environment, and led to the convergence of spatial strategies of the large innovative firms and the development strategies of regional and local governments. This process contributes toward the integration of the external firms within local productive systems and, therefore, large innovative firms can play a relevant role in endogenous development processes. Although the convergence of strategies is not a phenomenon that can be generalized for all types of firms and territories, a new line of action opens up that permits improved productive restructuring and economic development, even in less favoured and peripheral regions.     

To Majority through the Search for Unanimity

The relative majority rule is characterized, when there are only two alternatives, in terms of axioms of unanimity, reducibility, ontoness (which expresses citizen sovereignty), and no veto power (a weakening of almost unanimity). The strongest axiom is reducibility, which embodies the preference aggregation procedure that successively synthesizes two divergent preferences until divergence disappears and, therefore, unanimity can be applied.     

Do Private Equity Investors Create Value for Italian Initial Public Offerings?

This study analyses the role of private equity (PE) backing in initial public offerings (IPOs) using a dataset of 227 companies that went public on the Milan Stock Exchange between January 1995 and December 2007. The evidence rejects the certification and monitoring hypotheses and provides considerable support for the market power hypothesis. In accordance with Chemmanur and Loutskina (2006) , we suggest that PE investors exploit their relationships with the key IPO market players to attract attention to the IPOs of firms backed by PE, thus obtaining a higher equity valuation (both in the IPO and in the secondary market).
