Financial development and growth: An empirical analysis

Over the last two decades several countries experienced currency crises. These were characterized both by a huge disruption of economic activity and an extreme speed of diffusion within countries. The financial turmoil happened in a period of very high degree of international financial integration. As a result financial liberalization was associated with greater incidence of crises and this brought an intense debate in both academic and policy circles about the consequences of free capital movements.     

Small firms in Portugal: a selective survey of stylized facts,economic analysis,and policy implications

I survey a number of stylized facts pertaining to the dynamics of firm entry, growth, and exit in competitive industries. I focus particularly on data for Portugal, although I also consider, for comparison purposes, data from other countries. I then present a series of theoretical models that attempt to explain the stylized facts and evaluate the welfare impact of market distortions. Finally, I derive a number of policy implications, all centered around the notion of economic mobility.

Portuguese emigration 1958-1985: some empirical evidence

Supplying work in the home country or abroad must be seen as the result of the same decisional process. If that is true, the same set of variables should be used to explain the participation in the labor market and the emigration rates.Based upon empirical results, we discuss some of the traditional conclusions of the economic literature. Our empirical results, for example, show that: 1) there is a strong support for considering home wages and the wages in the country of destination asymmetrically, 2) imperfections in the capital markets seem to play an important role when workers must pay for their moving expenses and 3) there is a differential in coefficients between the period before 1974 and after that date, as 1974 is the year most of the Central European countries changed their immigration policies.     

Price determination and dynamic adjustments: An inverse demand system approach to meat products in the United States

In this study the process of retail meat price determination is depicted in the form of an inverse demand system taking into consideration the dynamic adjustments present in monthly consumption data. The general dynamic framework identifies both long run and short run effects in a systematic manner and allows direct estimation of the long run price and scale flexibilities that are consistent with theory. The empirical application based on monthly U.S. meat products data provides reasonable and promising results.The authors are senior econometrician, Department of Risk Management, TRS, American Express Co., Phoenix, and assistant professor, Department of Applied Economics, University of Minnesota, St. Paul, respectively.

Sovereign-Wealth Funds: the institutional dimension

In the recent past, the operations of the capital-rich Sovereign-Wealth Funds (SWFs) went on increasing in the global capital markets. As the global economic crisis that started in 2007 deepened, SWF operations dramatically spurted, leading to further progressive increase in their significance for the global capital markets. For all appearances they are going to be important financial players in the foreseeable future. This article focuses on the basic concept of SWFs, their structure and operations. It attempts to analyze and elucidate on them. Notwithstanding the fact that SWFs are an instrument of enhancing liquidity and financial resource allocation in the international capital market, they managed to become a source of controversies. Consequently they became a source of escalation in financial protectionism in several advanced industrial economies, in particular the USA. The article concludes that this was unwarranted. Recently SWFs have attempted to device an array of best practices to improve the transparency of their global financial operations. These measures are expected to enhance the acceptance of SWFs as well as global recognition of their operations. They would also help in dispelling the negative image that SWFs have held in several advanced industrial economies.

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.

An overlooked explanation of the declining saving rate

With a socioeconomic model of the determinants of savings that takes into account variables reflecting the abrupt changes in the divorce rate that occurred during the 1970s and the 1980s in the U.S., the increase in women's participation in the labour force, and their greater investrnent in education, we explain part of the measured decline in the saving rate. The uncertainty generated by the increased likelihood of divorces encourages households and women, in particular, to substitute human capital to financial or physical capital for precautionary savings.The authors thank Anna J. Schwartz and Pierre Perron for helpful suggestions and Anne-Marie El Hakim for her dedicated assistance on this project.

Measuring environmental efficiency of industry: a case study of thermal power generation in India

Technical and environmental efficiency of some coal-fired thermal power plants in India is estimated using a methodology that accounts for firm’s efforts to increase the production of good output and reduce pollution with the given resources and technology. The methodology used is directional output distance function. Estimates of firm-specific shadow prices of pollutants (bad outputs), and elasticity of substitution between good and bad outputs are also obtained. The technical and environmental inefficiency of a representative firm is estimated as 0.06 implying that the thermal power generating industry in Andhra Pradesh state of India could increase production of electricity by 6/ while decreasing generation of pollution by 6%. This result shows that there are incentives or win–win opportunities for the firms to voluntarily comply with the environmental regulation. It is found that there is a significant variation in marginal cost of pollution abatement or shadow prices of bad outputs across the firms and an increasing marginal cost of pollution abatement with respect to pollution reduction by the firms. This result calls for the use of economic instruments like pollution taxes instead of command and control regulation used currently in India to reduce air pollution.

Usefulness of linear transformations in multivariate time-series analysis

Much progress has been made in recent years in multivariate time-series analysis. In this paper we summarize some of the methodological developments that are particularly relevant to empirical economics and highlight especially the usefulness of linear transformations in analyzing multivariate time series. The topics considered include vector ARMA models, principal component analysis, scalar component models, canonical correlation analyses, co-integration, and unit-root tests. We illustrate the methods considered by an example using Taiwan's interest-rate series and provide critiques of these developments.     

A system approach for measuring the euro area NAIRU

This paper addresses the issue of measuring the NAIRU for the euro area and assessing the robustness and precision of the obtained estimates. The empirical framework adopted is based on systems combining an Okun-type relationship between cyclical unemployment and the output gap with a Phillips curve and stochastic laws of motion for the NAIRU and potential output. Such systems have been estimated using Kalman-filter techniques. The results obtained point to an estimate of the area-wide NAIRU that is robust to changes in the underlying models. This robustness is shown to hold both in terms of the mean – i.e., the shape of the resulting NAIRU – and the variance of the process. The latter is derived through bootstrap exercises using the models alone or pooled together. The evidence found suggests that the increase in the aggregate NAIRU that took place in the early part of the sample period has come to a halt and may be about to be reversed.Jel classification: C11, C15, E31, E32The opinions expressed in this paper are those of the authors and do not necessarily reflect the views of the Institutions they belong to.

Retesting symmetry and homogeneity in a cointegrated demand system with bootstrapping: The case of meat demand in Greece

A small Almost Ideal Demand System is estimated for Greek meat consumption using the Johansen procedure in conjunction with parametric bootstrapping and Bartlett corrections. Asymptotic Wald and likelihood ratio tests broadly support the predicted number of cointegrating relationships but reject symmetry and homogeneity. Bootstrapping and Bartlett corrections give support to symmetry and homogeneity but give less support for the predicted number of cointegrating relationships.Jel classification: C32 D12First version received: September 2001/Final version received: March 2003     

Endogenous fertility, international migration and growth

An endogenous growth model with heterogeneous agents and endogenous rates of fertility is developed to study the relationships between population growth, human capital, migration and economic development. A variety of patterns of migration, from the migration of the unskilled to the brain drain is considered, where the decision to migrate reflects the agents’ optimising behaviour. The analysis yields implications which accord with the empirical evidence on the relationships between demography and development. Macroeconomic policy can foster growth by influencing labour mobility through taxation and the provision of public goods such as social infrastructure, sanitation, environmental control and medical research that affect locational preferences and child quality.

Policy matters. The long run effects of aggregate demand and mark-up shocks on the Italian unemployment rate

This paper estimates a VAR including labor productivity, real wage and unemployment rate, to identify the dynamic effects of technology, demand, and mark-up shocks, respectively, on the Italian labor market. Identification is achieved by imposing recursive restrictions on the matrix of long run multipliers. Our results show that both mark up and aggregate demand shocks permanently reduce the unemployment rate. Finally, technology shocks do not significantly affect the unemployment rate in the long run. These findings convey important policy implications: expansionary aggregate demand and deregulation policies reducing the mark up permanently decrease the Italian unemployment rate.Jel classification: C32, E32, J29This paper has been produced as part of a CEPR Research Network on New Approaches to the Study of Economic Fluctuations.

An empirical note about additive outliers and nonstationarity in Latin-American inflation series

This note shows the empirical dangers of the presence of large additive outliers when testing for unit roots using standard unit root statistics. Using recent proposed procedures applied to four Latin-American inflation series, I show that the unit root hypothesis cannot be rejected.Jel classification: C2, C3, C5I want to thank Pierre Perron for useful comments on a preliminary version of this paper.

Quarterly US unemployment: Cycles,seasons and asymmetries

This paper documents three stylized facts for the quarterly unemployment rate in the United States. Firstly, unemployment is asymmetric over the business cycle, i.e. it rises sharply in recessions and it falls slowly in expansions. Secondly, its seasonal fluctuations are not constant across the two business cycle stages in the sense that there is less seasonality in recession periods. Thirdly, the effect of shocks to the unemployment rate in expansions seem transitory, while this effect is permanent in recessions. Some implications of these stylized facts for empirical macroeconomics and seasonal adjustment are discussed.
