Habit formation and fiscal transmission in open economies

In this paper we analyze the ability of an open economy version of the neoclassical model to account for the time-series evidence on fiscal policy transmission. Revisiting the evidence, we find that i) government spending raises output, while inducing a simultaneous decline of investment and the current account and ii) the responses of output and investment are more muted in more open economies while current account deficits tend to be larger. Turning to the model, we explore the role of habit formation for fiscal policy transmission. Specifically, we show that the model can account for the evidence if consumption behavior is characterized by habit formation and the terms of trade adjust endogenously.     

Psychological Points of Equilibrium in Asset Valuation During Market Bubbles

This paper presents the concept of psychological point of equilibrium (PPE), which is a mental state achieved by average investors when trying to make decisions during market bubble's inflationary stages. The PPE results from an interplay between agents acting in a volatile market that is characterized by predatory behaviors. Prior to the 2008 subprime crisis, average investors are assumed to have displaced their logical PPEs in large part as a consequence of their attraction towards predatory mortgages and teaser rates. A better understanding of average investor's vulnerabilities may help governments to implement more efficient measures aimed at curving predatory behaviors.     

Do flexible exchange rates facilitate external adjustment? A dynamic approach with time-varying and asymmetric volatility

This paper revisits the claim that flexible exchange rates facilitate external adjustment. While previous studies have used exchange rate regime as a proxy for exchange rate flexibility, in this study there is evidence of ARCH effects in exchange rate, and thus GARCH models are employed to estimate volatility. A dynamic panel data model is then specified, and the Arellano-Bond estimator and the Blundell-Bond estimator are employed to estimate the effect of exchange rate flexibility on the speed of adjustment of current account in a panel of 28 emerging and developing economies. There is robust evidence that flexible exchange rates indeed facilitate smoother adjustment of current account imbalances.     

On the way to recovery: A nonparametric bias free estimation of recovery rate densities

In this paper we analyse recovery rates on defaulted bonds using the Standard & Poor's/PMD database for the years 1981–1999. Due to the specific nature of the data (observations lie within 0 and 1), we must rely on nonstandard econometric techniques. The recovery rate density is estimated nonparametrically using a beta kernel method. This method is free of boundary bias, and Monte Carlo comparison with competing nonparametric estimators show that the beta kernel density estimator is particularly well suited for density estimation on the unit interval. We challenge the usual market practice to model parametrically recovery rates using a beta distribution calibrated on the empirical mean and variance. This assumption is unable to replicate multimodal distributions or concentration of data at total recovery and total loss. We evaluate the impact of choosing the beta distribution on the estimation of credit Value-at-Risk.     

How organisational image affects employee attitudes

Organisational image has mostly been studied using an external perspective focused on strategy and marketing issues. Given its salience in employees' symbolic environment, however, image may also have internal as well as external consequences. Yet, the potential impact of image on internal HR aspects has received only pminimal interest from researchers. This article presents the results of a study that explored the impact of perceived external prestige (PEP) on three individual outcomes: job satisfaction, affective organisational commitment and affective well‐being at work. It is based on a survey of 527 French managers. The findings show that all individual outcomes are related to PEP. Moreover, it was found that the impact of corporate image on some of the outcomes was stronger for individuals working in sales/marketing than for other employees.     

Brain Drain in Developing Countries

An original data set on international migration by educationalattainment for 1990 and 2000 is used to analyze the determinantsof brain drain from developing countries. The analysis startswith a simple decomposition of the brain drain in two multiplicativecomponents, the degree of openness of sending countries (measuredby the average emigration rate) and the schooling gap (measuredby the education level of emigrants compared with natives).Regression models are used to identify the determinants of thesecomponents and explain cross-country differences in the migrationof skilled workers. Unsurprisingly, the brain drain is strongin small countries that are close to major Organisation forEconomic Co-operation and Development (OECD) regions, that sharecolonial links with OECD countries, and that send most of theirmigrants to countries with quality-selective immigration programs.Interestingly, the brain drain increases with political instabilityand the degree of fractionalization at origin and decreaseswith natives' human capital.     

The Action Logics of Environmental Leadership: A Developmental Perspective

This article examines how the action logics associated with the stages of consciousness development of organizational leaders can influence the meaning, which these leaders give to corporate greening and their capacity to consider the specific complexities, values, and demands of environmental issues. The article explores how the seven principal action logics identified by Rooke and Torbert (2005, Harvard Business Review 83(4), 66–76; Opportunist, Diplomat, Expert, Achiever, Individualist, Strategist and Alchemist) can affect environmental leadership. An examination of the strengths and limitations of these action logics reveals the relevance of the so-called post-conventional stages of consciousness to the recognition and effective management of complex environmental issues. Suggestions are also made for promoting organizational contexts conducive to the development of a post-conventional environmental leadership.     

Market size and pharmaceutical innovation

This article quantifies the relationship between market size and innovation in the pharmaceutical industry using improved, and newer, methods and data. We find significant elasticities of innovation to expected market size with a point estimate under our preferred specification of 0.23. This suggests that, on average, $2.5 billion is required in additional revenue to support the invention of one new chemical entity. This magnitude is plausible given recent accounting estimates of the cost of innovation of $800 million to $1 billion per drug, and marginal costs of manufacture and distribution near 50%.     

QUANTIFYING THE LAFFER CURVE ON THE CONTINUED ACTIVITY TAX IN A DYNASTIC FRAMEWORK*

It is argued that the tax on continued activity should be removed by implementing actuarially fair schemes. However, these schemes cannot fund the expected Social Security (SS) deficit. This article proposes to give individuals a fraction of the actuarially fair incentives in the case of postponed retirement. SS faces a trade‐off between giving enough incentives to make individuals delay retirement and giving little increase in pensions in order to help finance its expected deficit. This trade‐off is captured by a Laffer curve. Finally, when the SS system aims to maximize welfare, the optimal tax on postponed retirement is still strictly positive.     

Voluntary contributions to a joint project with asymmetric agents

We revisit Admati and Perry (1991)'s model of voluntary contributions to a joint project. Their main result that equilibrium contributions are small appears not to be robust to the introduction of asymmetries.
