Dissensus, death and division

2009

The modeling of switching systems describing networks where death and duplication processes occur is described. A dissensus protocol, complementary to consensus protocol, is introduced and the convergence or divergence of the agents' state evolution is studied. We discuss some properties of the topology reached by the network when different rules of duplication and inheritance are implemented.

High Frequency Data Analysis in an Emerging and a Developed Market

2002

We compare distributional properties of high frequency (tick by tick) returns of stocks traded at the NASDAQ, NYSE, and BSE (Budapest Stock Exchange). In particular, we model returns with a mixture of a degenerate (zero) and a symmetric stable distribution. We measure time with the number of successive price changes on the market and study the convergence of the index of stability on increasing time horizons. We apply results to calculate expected waiting times to reach given levels of value at risk.

The Role of the Exchange Rate Regime in the Process of Real and Nominal Convergence

2013

During the last decade, economists have intensively searched for evidence on the importance of the Balassa-Samuelson (B-S) hypothesis in explaining nominal convergence. One general result is that B-S can at best explain only part of the excess inflation observed in the European catching-up countries, which suggests that other factors may be at play. In these and related studies, however, the potential role of the exchange rate regime in affecting price convergence in Europe has been overlooked. In this respect, we claim that the choice of the exchange rate regime has decisively affected the path of nominal convergence. To show this, we first model the (endogenous) choice of the exchange rat…

Producer Prices in the Transition to a Common Currency

2006

We analyze producer price developments in the transition from a national exchange rate regime to a monetary union. The focus is on the European Economic and Monetary Union (EMU). Stylized facts witness about an exploding gaps in producer-price inflation during the years immediately following the completion of the EMU. Price convergence is found to be an important driver throughout the entire euro period (1999-2005), but with no significant differences in speed compared to the pre euro period. Productivity growth had its primary effect in the first years and effective exchange-rate changes in the later years of the euro period.

A new result on impulsive differential equations involving non-absolutely convergent integrals

2009

AbstractIn this paper we obtain, as an application of a Darbo-type theorem, global solutions for differential equations with impulse effects, under the assumption that the function on the right-hand side is integrable in the Henstock sense. We thus generalize several previously given results in literature, for ordinary or impulsive equations.

Terms of trade, catch-up, and home-market effect: The example of Japan

2007

Abstract This paper explores theoretically and empirically the medium- and long-run relation of the terms of trade (ratio of traded goods prices) and economic growth of a pair of countries—one of which experiences a major catch-up process towards the other. Two theoretical interdependencies between the terms of trade and economic growth are offered: the home-market effect and the productivity-shock effect. These two effects are tested against each other in a cointegration analysis on data for Japan and the US from 1971 until 1997. Income is cointegrated with the terms of trade. The relevant empirical channel is the home-market effect. However, financial-market effects appear also to be rele…

Exchange Rate and Interest-Rate Driven Competitive Advantages in the EMU

2002

Real exchange and interest rates may still fluctuate inside the EMU and give rise to changes in competitiveness. We find, in contrast to what is generally expected, no convergence in these variables after the introduction of the euro. On the contrary, a divergence is found that is extraordinary when compared to the preceding 40 years. The magnitude of the divergence should urge on a wave of restructuring in the EMU, conditioned upon adequate policy responses. The worst-case scenario involves a flight to structural support and protectionism, challenging the whole idea of the EMU.

Gender discrimination and intergenerational transmission of preferences

2004

This paper provides an explanation for the existence of gender discrimination in the labour market focusing on the intergenerational transmission of preferences related to the attitude of women towards jobs and family. Changes in women's preferences over generations depend on the socialization efforts of their parents which in turn are influenced by both the firm's expected recruitment policy and the expected utility from household care. We obtain two types of steady state equilibria: the discriminatory equilibrium, in which women are segregated to low-paid jobs, and the non-discriminatory equilibrium, in which women are hired in highly-paid jobs. The conditions of convergence to each equil…

Price Convergence in the European Union

2004

This study investigates the relationship between market integration and price convergence in international markets. Using a panel data set of consumer price indices (general and by groups and classes), it examines how European market integration has affected cross-country dispersion in the European Union.
