Inflation and output volatility under asymmetric incomplete information

The assumption of asymmetric and incomplete information in a standard New Keynesian model creates strong incentives for monetary policy transparency. We assume that the central bank has better information about its objectives than the private sector, and that the private sector has better information about shocks than the central bank. Transparency has the potential to trigger a virtuous circle in which all agents find it easier to make inferences and the economy is better stabilised. Our analysis improves upon existing work by endogenising the volatility of both output and inflation. Improved transparency most likely manifests itself in falling output volatility.     

What's the monetary value of distributive justice?

This paper proposes a model that can be implemented to estimate the willingness to pay for distributive justice, defined as distribution according to desert. We derive a formula that allows one to recover the willingness to pay for distributive justice from fiscal data and the estimated coefficients of a probit regression. Using this formula and data from a 1998 Gallup Social Audit, we find that on average the monetary value of justice for US households amounts to about one fifth of their disposable income. Moreover, we find evidence of markedly heterogeneous preferences for justice that differ by race and education.     

Analysis of default data using hidden Markov models

The occurrence of defaults within a bond portfolio is modelled as a simple hidden Markov process. The hidden variable represents the risk state, which is assumed to be common to all bonds within one particular sector and region. After describing the model and recalling the basic properties of hidden Markov chains, we show how to apply the model to a simulated sequence of default events. Then, we consider a real scenario, with default events taken from a large database provided by Standard & Poor's. We are able to obtain estimates for the model parameters and also to reconstruct the most likely sequence of the risk state. Finally, we address the issue of global versus industry-specific risk factors. By extending our model to include independent hidden risk sequences, we can disentangle the risk associated with the business cycle from that specific to the individual sector.     

Assurance Services for Sustainability Reports: Standards and Empirical Evidence

This article contributes to the growing scholarship on the topic of assurance services for sustainability reports. We first synthetically illustrate the main international standards for the implementation of assurance services regarding the subject documents. The second part of our article is an empirical analysis of reports drawn up on the basis of the current Global Reporting Initiative 2006 guidelines, and looks at how effectively these standards have been implemented, analyzing the different typologies of assurance statement.     

A theory of tolerance

We propose a theory of tolerance where endogenous lifestyles and exogenous traits are invested with symbolic value by people. Value systems chosen by parents for their children affect the esteem enjoyed by individuals in society. Intolerant individuals attach all symbolic value to a small number of attributes and are irrespectful of people with different ones. Tolerant people have diversified values and respect social alterity. We study the formation of values attached to various types of attributes and identify circumstances under which tolerance spontaneously arises. Policy may affect the evolution of tolerance in distinctive ways, and there may be efficiency as well as equity reasons to promote tolerance. An empirical investigation of tolerance of homosexuality demonstrates that our theory helps to shed light on survey data of endorsed values.     

Competition and Efficiency in Health Care: An Analysis of the Italian Case

In this paper we look at the Italian NationalHealth System as a case study, in order to investigate whethercompetition exerts positive effects on the efficiency of hospitals.Using the DEA technique we measure the efficiency of Italianhospital production; secondly, we take a regression analysisapproach to analyse its determinants. A general conclusion stemmingout of the analysis is that competition is not a value per seand that its effects on hospitals' performance are affected bythe rules governing the health system.     

Lessons from the ECB Experience: Frankfurt Still Matters!

This paper compares the European Central Bank's (ECB) conduct of monetary policy (1999–2005) with that of the Bundesbank (after the German Unification: 1990–1998) in order to test the hypothesis of an ECB with 'Bundesbank's preferences' put forward in the theoretical literature ( Alesina and Grilli, 1993 ; Fatum, 2006 ). Econometric tests and simulations based on monetary policy reaction functions show that the continuation of the former Bundesbank regime is supported by the data. Given this empirical evidence we discuss the lessons for future Monetary Unions stemming from the ECB experience.     

Social Organization in an Endogenous Growth Model

We develop an endogenous growth model in which individuals form matches in order to consume goods that are not explicitly traded. The matching process endogenously generates a concern for relative wealth and is thereby beneficial for capital accumulation and economic growth. We then study how social segmentation in the matching process affects economic growth. Under strong segmentation, social competition over mates occurs inside homogeneous groups. This homogeneity increases the severity of the "rat race" of wealth accumulation and fosters economic growth.     

New Deal für Deutschland als wirtschaftspolitische Alternative

Mit der Globalisierung und dem technischen Wandel sind Chancen und Risiken verbunden. Wer profitiert von dem ?konomischen Wandel und wer geh?rt zu den Verlierern? Welche Probleme ergeben sich aus einer m?glichen Spaltung der Gesellschaft? Wie sollte die Wirtschaftspolitik auf diese Herausforderungen reagieren? Professor Giacomo Corneo pl?diert für einen „New Deal“. Prof. Dr. Dr. Giacomo Corneo, 43, ist Inhaber des Lehrstuhls für ?ffentliche Finanzen an der Freien Universit?t Berlin.
