Problemas en la estimación y en el contraste de los rendimientos anormales a largo plazo: Estado de la cuestión
2002
-Jose.E.Farinos@uv.es -Ana.M.Ibanez@uv.es El paradigma de la eficiencia ha sido puesto en entredicho en las últimas décadas como consecuencia de la obtención de rendimientos anormales, estadística y económicamente significativos, durante amplios periodos de tiempo tras algunas importantes decisiones empresariales. No obstante, los problemas conceptuales y estadísticos que presenta la medición y contrastación de los rendimientos anormales a largo plazo ha supuesto que la evidencia obtenida pase a calificarse como anomalía. Dada la escasa proliferación de este tipo de estudios en nuestro mercado y el desafortunado desarrollo de algunos de los existentes, en este trabajo presentamos estos prob…
The cost of equity and exchange listing evidence from the French stock market
1997
We reconsider the behaviour of prices around the period close to the listing on the Marché à Règlement Mensuel (RM). First, an event study based on a sample of 60 firms has been set up to test the existence of the exchange listing effect on the French market. Then we discuss and test the financial reasons which can justify abnormal returns around the announcement day and the day of the listing. We explore four reasons to explain the impact of the stock exchange listings: one is the informative content of the operation which induces an upward revision of the future earnings. Three other hypotheses rely on a decrease in the discount rate originated by less risky cash flows, an increase in tra…
Regional Integration in Trade Theory
2021
Given widespread scepticism in trade economics about the value of RECs comprised of developing countries, the formal theory of regional economic integration is critically examined in four stylized configurations. Based on the overarching logic of trade creation and diversion, the usual diagrammatic treatment of tariff effects is critically discussed in terms of its numerous shortcomings. A single-country and REC-wise diagrammatic treatment of tariffs in the presence of increasing returns is proposed to allow quantitative assessment of the arguably most promising case for South-South RECs. Building on the literature, the cases of full and incomplete specialization within a regional group are…
Producer Services and the Current Account
2022
Abstract In this paper, we present evidence that countries which experienced a larger expansion of services as a share of GDP in recent years exhibited lower current account balances. We argue that this relationship is compatible with the notion that producer services raise aggregate productivity by enhancing increasing returns to specialization, and we develop a model in which the deregulation of the services industry results in higher GDP growth, a reallocation of resources into the services industry, and a temporary current account deficit. We demonstrate that our theoretical argument is supported by the data, even if we control for a multitude of other factors that potentially affect th…
Time-varying causality between crude oil and stock markets: What can we learn from a multiscale perspective?
2017
This paper investigates the presence of time-varying causal linkages in mean and variance between oil price changes and stock returns for six major oil-importing countries (France, Germany, Italy, Spain, the UK and the US) in a multiscale framework that combines wavelet analysis and a modified version of the dynamic causality test of Lu, Hong, Wang, Lai, and Liu (2014). The results show significant bidirectional causal relations between oil and stock markets at the different time horizons for all countries. The causal links tend to be stronger at coarser scales and in periods of financial turmoil, mainly during the recent global financial and European sovereign debt crises. This evidence pr…
Regional inequalities, economic crises and policies: an international panel analysis
2021
This paper examines the effects of economic downturns on regional inequalities. In a sample of 25 OECD countries for 1990–2014 period, we show that economic downturns are associated with a significant and long-lasting reduction in regional inequalities. Expansionary fiscal policy as well as higher share of the European development (cohesion) funds facilitate the response of lagging regions to negative nation-wide shocks, contributing to further stimulate the reduction in regional disparities. Additional evidence suggests that the effect of downturns tends to be larger in economies with a higher initial level of regional disparities in unemployment and human capital endowment.
The evolution of returns to education in Spain 1980-1991
1998
STT Working Paper, n°01-99 (Université d'Orléans), janvier 1999; Based on data from the 1980 and 1990 Household Surveys, we analyze educational expansion in Spain and estimate earnings equations for male family heads ; then rates of return to education in both years are compared. Furthermore we decompose the over-all average earnings differential over time to verify to what extent the magnitude of changes is due to variations in the characteristics of the working population during the 1980-1991 period, and how much of that differential is explained by differences in the pay structure.
A wavelet analysis of the ripple effect in UK regional housing markets
2021
Abstract The paper aims at gaining insights on the spatio-temporal mechanism of house price spillovers, also known as ripple effect, among 12 UK regional housing markets, over the period 1973–2018. From a policy perspective, it is essential to discriminate if the effects of a shock decay more slowly along the geographical dimension as compared to the decay along the time dimension. We enter the debate in a novel manner by using some wavelet analysis tools (wavelet coherence and phase differences amongst others) which reveal the spectral characteristics of a series and show how different periodic components of housing returns evolve over time. Results are interesting. Spillovers from London …
Nonlinear dynamics of interest rate and inflation
2004
According to several empirical studies, US inflation and nominal interest rates, as well as the real interest rate, can be described as unit root processes. These results imply that nominal interest rates and expected inflation do not move one-for-one in the long run, which is not consistent with the theoretical models. In this paper we introduce a nonlinear bivariate mixture autoregressive model that seems to fit quarterly US data (1952 Q1 – 2000 Q2) reasonably well. It is found that the three-month treasury bill rate and inflation share a common nonlinear component that explains a large part of their persistence. The real interest rate is devoid of this component, indicating one-for-one m…
Stock Returns and Exchange Rate Volatility Spillovers in the MENA Region
2010
In this article, we examine the presence of volatility spillovers between nominal exchange rates and stock returns in three MENA countries: Egypt, Morocco and Turkey. The multivariate GARCH model we use does not produce evidence of cross-market effects for the general stock indices returns. Nevertheless, bidirectional shock and volatility spillovers between exchange rates and stock returns exist at the industry sector level. These findings are more pronounced in Egypt and Turkey. The different results are due to the different exchange rate regimes/policies adopted by the three countries. While exchange rates in Egypt and Turkey were allowed to float, Morocco followed a more tightly managed…
