Seminario 14/26: M.A.CARNERO (UA) – Identification of asymmetric conditional heteroskedasticity in the presence of outliers

img1979136_Autoregressive-conditional-heteroskedasticity_osnova_Teorii_Volatilnosti

ABSTRACT: The identification of asymmetric conditional heteroscedasticity is often based on sample cross-correlations between past and squared observations. In this paper we analyse the effects of outliers on these cross-correlations and, consequently, on the identification of asymmetric volatilities. We show that, as expected, one isolated big outlier biases the sample cross-correlations towards zero and hence could hide true leverage…

Seminario 14/25 – F.Alcalá (UMU): Time to Consume, Consumption Quality and Hours Worked

consumo

ABSTRACT: The quality dimension of consumption plays a distinctive and important role in many economic areas. This paper provides a new approach to the demand for quality building from the fact that consumption has to be combined with time to produce utility. Focusing on the implications of this approach on the labor supply, the paper…

Seminario 14/24: S. Álvarez (UMU) – Voluntary early exercise and performance-vested option grants: an analysis of the incentive effects.

lee-lorenz-hold-it-we-almost-forgot-your-backdated-stock-options-new-yorker-cartoon1

ABSTRACT: Classical option pricing models are not well suited to the valuation of executive stock options (ESOs) and their incentive effects. The special characteristics of ESOs make standard methods difficult to apply to these options. The Wu-Lin model is a completely analytical expression based on the common feature of attaching performance targets to option vesting….

Seminario 14/23 – Fernando BRONER (UPF,MIT): Sources of Comparative Advantage in Polluting Industries

contaminacion ladrillo

Abstract: We study the determinants of comparative advantage in polluting industries. We combine data on environmental policy at the country level with data on pollution intensity at the industry level to show that countries with laxer environmental regulation have a comparative advantage in polluting industries. Further, we address the potential problem of reverse causality. We…

Seminario 14/22 – Enrique SENTANA (CEMFI): Is a normal copula the right copula?

stocksii

Abstract   Nowadays copulas are extensively used in economic and finance applications, with the Gaussian copula being very popular despite ruling out non-linear dependence, particularly in the lower tail. We derive computationally simple and intuitive expressions for score tests of Gaussian copulas against Generalised Hyperbolic alternatives, which include the symmetric and asymmetric Student t, and Hermite polynomial expansions. We…

Seminario 14/21 – Laura HOSPIDO (BDE): The Cycle of Earnings Inequality: Evidence from Spanish Social Security Data

Desigualdad salarial

Abstract We use detailed information on labor earnings and employment from Social Security records to document earnings inequality in Spain from 1988 to 2010. Male earnings inequality was strongly countercyclical: it increased around the 1993 recession, showed a substantial decrease during the 1997-2007 expansion and then a sharp increase during the recent recession. These developments were partly driven by…

Seminario 14/20 – Luis CORCHON (UC3M): Dynamic Contests with Bankruptcy: The Despair Effect

bankruptcy

Abstract In this paper we analyze a two period contest in which agents may become bankrupt at the end of the first period. A bankrupt agent is excluded from the contest in the second period of the game. We investigate the existence of a subgame perfect equilibrium in pure strategies. We distinguish between a borrowing…

Seminario nº19: Approval Voting Committees with Gender Balanced Representativeness

igualdad-de-género1-620×330

Abstract:  La Comisión de Derechos de la Mujer e Igualdad de Género del Parlamento Europeo, en un informe de 2012 sobre la representación de las mujeres en los procesos de decisiones políticas, recomienda reformas en los sistemas electorales para que favorezcan la representación femenina. El mencionado informe reconoce que los sistemas electorales tienen un papel…

Seminario nº18: The two greatest, Great Recession vs. Great Moderation

Great-Recession-02

Abstract: The collapse of the global economy in 2008, following the outbreak of the financial crisis, and the ensuing economic developments of the so-called Great Recession (GR), led many economists to suggest that the relative oasis in which we had lived for almost a quarter of a century, known as the Great Moderation (GM), had indeed…
