Entry, exit and business cycles in a general equilibrium model

This paper studies the role of entry and exit in the short run behavior of a general equilibrium model with industry dynamics. For tractability, and to preserve potential asymmetries in the impulse responses, I focus on the transition dynamics of the economy after shocks. Entry and exit are found to be insensitive to productivity shocks of reasonable magnitude. Moreover, the dynamics of GDP are insensitive to fluctuations in entry and exit rates, and any asymmetries are negligible. As an application of the model, the paper also asks whether firing costs may interact with entry and exit to affect transition dynamics after shocks, finding that they do not.     

ESTIMATION WITH CENSORED REGRESSORS: BASIC ISSUES*

We study issues that arise for estimation of a linear model when a regressor is censored. We discuss the efficiency losses from dropping censored observations, and illustrate the losses for bound censoring. We show that the common practice of introducing a dummy variable to “correct for” censoring does not correct bias or improve estimation. We show how censored observations generally have zero semiparametric information, and we discuss implications for estimation. We derive the likelihood function for a parametric model of mixed bound‐independent censoring, and apply that model to the estimation of wealth effects on consumption.     

People, cities, growth and technological change : From the golden age to globalization

The concept of economic development appeared during the postwar period as the basis and the source of a very strong hope of eradicating extreme poverty from the face of the Earth. All along the three first decades of this period—the second half of the 20th century—this promise did not seem questionable. It was thought that there were clear signs that material progress reaching larger sectors of the population and economic growth were parallel processes, linked to urbanization. A new style was thus established—that of modern large cities. However, the dynamics of this period appears to be strongly associated with the economic activity related to the basic construction of one's own lifestyle. The effects of structural market saturation and the limits of the redistribution of income began to be noticed in as far back as the end of the 1960s, and even more clearly so towards the end of the 1970s. That was the moment when population growth in the megalopolises and large cities in general began to become stable and even to decline in absolute value. It was also the time when the acceleration of technological innovation began to play a major role in development policies, while low social inclusion and marginalization problems became evident. This paper delves into this hypothesis on the basis of ample empirical evidence. Numerous conclusions are drawn from the analysis, which are useful for a serious restatement of the controversial issue of Sustainable Development.     

Approccio di tipo max-min per la determinazione del prezzo psicologico in caso di incertezza

Si considera un modello, già noto in letteratura, in cui un produttore deve determinare il prezzo unitario di vendita del bene che produce. Scopo di questo lavoro è generalizzare il modello suddetto al caso di incertezza nell'informazione e studiare l'esistenza delle soluzioni del problema che consegue da tale generalizzazione.

Summary Let us consider a model, known in literature, in which a producer must determine the unitary selling-price of the commodity that he produces. Purpose of this paper is to generalize such a model for case of uncertainty in the information and to study the existence for the problem connected with this generalization.

     

Elections and selection: The role of political ideology in selection decisions

Political ideology is a central belief that drives individuals' behavior not just in the voting booth but also in other aspects of life. As political divisiveness in society has increased, the ramifications of this shift may permeate organizations ultimately affecting how individuals interact with one another. Through the lens of social cognition and person-organization fit, this paper considers the effect of political ideology of job applicants in selection decisions by discussing 1) the definition of political ideology and subsequent stereotyping, 2) the increasing divisiveness rooted in political ideology, 3) the implication in selection decisions influenced by political ideology, and 4) the consequences for firm level diversity. Further, a model is provided to illustrate the relationship of political ideology to various phases of the selection process. Propositions to foster further study of these phenomena are provided within.     

Differential Impacts of Structural and Cyclical Unemployment on Mortgage Default and Prepayment

The Great Recession (the fourth quarter of 2007 through the second quarter of 2009) has been characterized by high rates of foreclosures and unemployment. Using a sample of community reinvestment loans, we examine the impact of structural unemployment and cyclical unemployment on mortgage terminations (default and prepayment). We find that mortgage default and prepayment are more sensitive to changes in the structural component of the local unemployment rate than in the cyclical component. In addition, depending on whether structural unemployment rates are high or low, borrowers and lenders react differently to the incentives to terminate a loan.     

Hierarchical Modelling of Disparities in Preferences for Redistribution*

We evaluate the magnitude of the disparities in the demand for redistribution across European countries and American states during the 2000s. Modelling the demand for redistribution in a multilevel framework, we identify the determinants that contribute the most in predicting support for redistribution. We observe that individual characteristics and contextual variables are associated with demand for redistribution in the same way in Europe and in the US, whereas others exert different influences on the probability of supporting redistribution. We find important differences from some well‐established evidence obtained from data collected for the 1980s and the 1990s.     

MONETARY POLICY WITH INVESTMENT–SAVING IMBALANCES

Financial instability is the new challenge for monetary policy. Most studies indicate that financial crises follow prolonged unwinding of investment–saving imbalances (ISI). These phenomena are not contemplated by the standard theoretical framework of continuous intertemporal equilibrium. This paper's aim is to take a first step into the analysis of monetary policy in the context of ISI. First, a dynamic model of a flex‐price, competitive economy is presented where ISI are allowed to develop. Second, upon introducing different types of Taylor rules, some indications for the conduct of monetary policy emerge, which are at variance with the standard view.     

An evolutionary CAPM under heterogeneous beliefs

Heterogeneity and evolutionary behaviour of investors are two of the most important characteristics of financial markets. This paper incorporates the adaptive behaviour of agents with heterogeneous beliefs and establishes an evolutionary capital asset pricing model (ECAPM) within the mean-variance framework. We show that the rational behaviour of agents switching to better-performing trading strategies can cause large deviations of the market price from the fundamental value of one asset to spill over to other assets. Also, this spill-over effect is associated with high trading volumes and persistent volatility characterized by significantly decaying autocorrelations of, and positive correlation between, price volatility and trading volume.     

Patients' migration across regions: the case of Italy

This article analyses patient mobility across Italian regions. A modified gravity model of patient migration is specified and estimated using panel observations covering mobility and other main regional quality indicators over the period 1994–1997. Despite the high level of aggregation due to data constraints, the empirical findings show that in Italy there is wide scope for quality-driven mobility while income determines the quality of the service offered.
