Fractional integration and business cycle features

We show in this article that fractionally integrated univariate models for GDP lead to a better replication of the main business cycle characteristics. We firstly show that the business cycle features are clearly affected by the degree of integration as well as by the other short run (AR, MA, etc.) components of the series. Then, we model the real GDP in the UK and the US by means of fractionally ARIMA (ARFIMA) model, and show that the time series can be specified in terms of this type of model with orders of integration higher than one but smaller than two. Comparing the ARFIMA specifications with those based on ARIMA models, we show via simulations that the former better describe the business cycles features of the data.Jel classification: C12, C15, C22The authors want to thank two anonymous referees for wise remarks.

Measuring common cyclical features during financial turmoil: Evidence of interdependence not contagion

This paper develops a test of contagion in financial markets by considering a measure of co-movement based on the notion of common cycles to detect short-run co-movements between a set of time series. We apply our methodology to the international effects of the 1994 Mexican peso crisis and the 1997 Asian crisis. Our results can be interpreted as evidence of a high level of market co-movement during all states of the world and, therefore, question the hypothesis of shift-contagion in the transmission of financial shocks during the 1997 Asian crisis, and to a lesser extent, the 1994 Mexican crisis.     

The 1985 to 1994 Global Real Estate Cycle: An Overview

The globalization of financial markets is affecting real estate markets. During the period 1985 to 1994, a large number of countries experienced strong real estate booms that peaked around 1989 followed by severe asset price deflation and an output contraction that usually lasted until 1994. Global finance appears irreversible. Should we also expect the recurrence of real estate cycles of strong amplitude? Or does this first global cycle represent a one-time adjustment to global integration happening in many countries simultaneously? To facilitate further comparative analyses, this article inventories the international and domestic factors, in their macroeconomic and intrinsic real estate cycle dimensions, that contributed to this strong global cycle. This overview has three threads: What triggered this first global cycle? What has been its impact? Are there lessons for countries that are not yet fully integrated into global capital markets such as semireformed socialist economies, newly industrialized economies, and other developing countries?     

The demand for housing in developing countries: The case of Korea

This paper presents the results of an analysis of urban housing demand for Korea taking into account the most recent findings of housing demand analysis concerning specification and aggregation biases. In order to obtain correctly specified demand functions, a procedure based on a model of the housing market originally proposed by Muth is used. Drawing on the detailed land information available in Korea, this procedure permits the calculation of an individual price per unit of housing services for each household. The results show conclusively that both the income and price elasticity of the demand for housing services in Korea are comparable to those found in the United States: the income elasticity is smaller than one and the price elasticity is negative and smaller than one in absolute value. Given the number of countries found within the per capita income range between Korea ($700) and the United States ($7800), the finding that these two countries have comparable demand elasticities is of major significance: in the absence of good national estimates, the order of magnitudes found here would be used for other country analyses.     

The creation of complicity a semiotic analysis of an advertising campaign for Black & White whisky

A qualitative pre-test study, employing the structured semiotic methodology of Greimas and the Paris school, was conducted on four print advertisements conceived for a Black & White whisky campaign, and this article presents the major findings. Both the content and expression of the advertisements are examined, in terms of elementary oppositions, of narrative organization, of cultural values, and of linguistic and plastic manifestations. Finally, the ironic quality of the enunciation, playing on cultural stereotypes, is shown to demonstrate an equivalence between the ‘author’ of the campaign and the target public envisaged.     

Optimal Monetary Policy, Taxes, and Public Debt in an Intertemporal Equilibrium

This article is devoted to a study of the optimal monetary and fiscal policies within the framework of an overlapping generations model with cash-in-advance constraints. We first characterize the intertemporal equilibrium. Then we show how to decentralize the optimal growth path using available policy instruments (i.e., labor income and capital taxes, public debt, money supply). Between the four instruments: wages and capital taxes, debt and monetary policy, one is redundant among the three last which implies that the Friedman Rule is only a special case.     

Economics of residential crowding in developing countries

In an attempt to eliminate residential crowding, most countries pursue the policy objective of providing one dwelling unit per household. However, we know little about the demand for various dimensions of housing space which affects the levels of crowding. This paper analyzes the nature of demand for residential space and multiple occupancy in order to identify the major determinants of crowding. The result indicates that to a great extent crowding is explained by economic factors and that the current policy approach to elimination of crowding, which emphasizes one dwelling per household, is not likely to be effective.     

Mean Reversion of Short‐run Interest Rates in Emerging Countries*

In this paper we examine the stochastic behavior of short‐run interest rates in several emerging countries using fractional integration techniques. We allow for a much richer flexibility in the dynamic behavior of the series than the classical representations based on I(0) or I(1) processes. It appears that for Singapore and Thailand nominal interest rates are mean‐reverting, whereas for Mexico, Malaysia, the Philippines, and Korea, the presence of a unit‐root test depends on the assumptions regarding the residuals’ autocorrelation. The results also suggest that uncovered interest parity (UIP) can only hold for two emerging countries. For the other countries, the stabilization policies in the aftermath of the currency crises have led to the rejection of the UIP hypothesis.
