Modelling money demand for a panel of eight transitional economies

In this article, we estimate money demand functions for a panel of eight transitional economies, using quarterly data for the period 1995:01 1995 to 2005:03. We find that real M1 and real M2 and their determinants, namely real income and short-term domestic interest rate, are cointegrated, both for individual countries as well as for the panel. Long-run elasticities suggest that consistent with theory, real income positively and nominal interest rate negatively impact real money demand. Our test for panel Granger causality suggests short-run bidirectional causality between M1 and M2 and their determinants. Finally, our tests for stability of the money demand functions reveal more cases of unstable money demand functions when M2 is used as a proxy for money demand.     

Is health care really a luxury in OECD countries? Evidence from alternative price deflators

This article examines whether real Health-care Expenditure (HE) is a luxury or necessity for Organization for Economic Co-operation and Development (OECD) countries over the period 1972 to 2004 within a panel unit root and panel cointegration framework. To realize this objective, we regress HE on real Gross Domestic Product (GDP), the proportion of the population aged over 65 (P65) and a time trend (T). We first present results for 18 countries where real HE per capita is obtained using a general GDP deflator. For these countries, we find that health care is a luxury for just one country. Next, we present results for eight countries where real HE is obtained using a specific health-care price index. When the general GDP deflator is replaced with a specific health-care price index, at least one of the GDP, P65 or T coefficients for the eight countries changes in a reasonably dramatic fashion, suggesting that the use of the GDP deflator introduces bias into the regression. We find that HE is a necessity in all eight countries. Given that the reliability of the GDP deflator results is questionable, on the basis of the results for the eight countries, we conclude that HE is a necessity.     

Interdependence and dynamic linkages between the emerging stock markets of South Asia

The present article examines the dynamic linkages between the stock markets of Bangladesh, India, Pakistan and Sri Lanka using a temporal Granger causality approach by binding the relationship among the stock price indices within a multivariate cointegration framework. We also examine the impulse response functions. Our main finding is that in the long run, stock prices in Bangladesh, India and Sri Lanka Granger‐cause stock prices in Pakistan. In the short run there is unidirectional Granger causality running from stock prices in Pakistan to India, stock prices in Sri Lanka to India and from stock prices in Pakistan to Sri Lanka. Bangladesh is the most exogenous of the four markets, reflecting its small size and modest market capitalization.     

Does environmental quality influence health expenditures? Empirical evidence from a panel of selected OECD countries

In this paper we examine the role of environmental quality in determining per capita health expenditures. We take a panel cointegration approach in order to explore the possibility of estimating both short-run and long-run impacts of environmental quality. Our empirical analysis is based on eight OECD countries, namely Austria, Denmark, Iceland, Ireland, Norway, Spain, Switzerland, and the UK for the period 1980-1999. We find that per capita health expenditure, per capita income, carbon monoxide emissions, sulphur oxide emissions and nitrogen oxide emissions are panel cointegrated. While short-run elasticities reveal that income and carbon monoxide emissions exert a statistically significant positive effect on health expenditures, in the long-run in addition to income and carbon monoxide, we find that sulphur oxide emissions have a statistically significant positive impact on health expenditures.     

Re-examining the “twin deficits” hypothesis: evidence from Australia

This paper re-examines the relationship between fiscal imbalances and net foreign borrowing. A general analytical approach is first developed which suggests that, other things equal, a rise (fall) in any advanced economy’s fiscal deficit should be fully matched by a rise (fall) in its net foreign borrowing, in accordance with the so-called twin deficits hypothesis. In the case of Australia, one of the world’s largest foreign borrower economies for its size, empirical estimation yields the novel result that Australia’s consolidated budget imbalance and its foreign borrowing were approximately twinned on the basis of quarterly data for 1983–2009, when Australia’s exchange rate floated and international capital mobility was high. This result is consistent with the conceptual framework and suggests that fiscal policy is likely to be ineffective as an instrument for influencing the real economy.     

Tourism demand modelling: some issues regarding unit roots,co‐integration and diagnostic tests

This paper investigates the all important issue of diagnostic tests, including unit roots and cointegration, in the tourism demand modelling literature. The origins of this study lie in the apparent lack in the tourism economics literature of detail concerning the diagnostic test aspect. Study of this deficiency has suggested that previous literature on tourism demand modelling may be divided into two categories: the pre‐1995 and post‐1995 studies. It was found that the pre‐1995 and some post‐1995 studies have ignored unit root tests and co‐integration and, hence, are vulnerable to the so‐called ‘spurious regression’ problem. In highlighting the key diagnostic tests reported by post‐1995 studies, this paper contends that there is no need to report the autoregressive conditional heteroskedasticity (ARCH) test, which is applicable only to financial market analysis where the dependent variable is return on an asset. More generally, heteroskedasticity is not seen as a problem in time‐series data. However, the reporting of a greater than necessary range of diagnostic tests — some of which do not have any theoretical justification with regard to tourism demand analysis — does not diminish the precision of the results or the model. This paper should appeal to scholars involved in tourism demand modelling. Copyright © 2003 John Wiley & Sons, Ltd.     

Testing for capital mobility: New evidence from a panel of G7 countries

In this paper, we test the savings-investment relationship for the G7 countries. Upon applying the Gregory and Hansen [Gregory, A.W., Hansen, B.E., 1996. Residual-based tests for cointegration in models with regime shifts, J. Econ. 70, 99-126] residual-based structural break test for cointegration for each of the G7 countries, we did not find any evidence of a cointegrating relationship between savings and investment. Extending the analysis to a panel framework, we could not establish any evidence of panel cointegration. Taken together, our findings suggest that capital in these G7 countries is highly mobile since no long-term relationship exists between savings and investment.     

Market liquidity risk factor and financial market anomalies: Evidence from the Chinese stock market

The Chinese stock market is an order-driven market and hence its characteristics are structurally different from quote-driven markets. There are no studies that consider the role of the market liquidity risk factor in determining cross-sectional stock returns in a model including financial market anomalies for order-driven markets. Our aim is to test whether financial market anomalies such as firm size, the book-to-market ratio, the turnover rate, and momentum both with and without the inclusion of the market liquidity risk factor in the case of the Chinese stock market can explain cross-sectional stock returns. The empirical framework is based on the model proposed by Avramov and Chordia (AC, 2006). Our main finding is that the AC model can capture financial market anomalies except momentum when we include the market liquidity risk factor on the Chinese stock market.     

Spread determinants and the day-of-the-week effect

In this paper, we examine the determinants of the dollar bid–ask spread for each day of the week over the period 1998–2008. Using a panel cointegration approach, we estimate the determinants of the spread in both the short-run and long-run. Our main findings suggest that: (1) there are day-of-the-week effects for certain groups of firms; (2) the panel error correction model also reveals day-of-the-week effects, and the speed of adjustment to equilibrium following a shock is faster on Fridays; and (3) the effects of volume and volatility on the spread are mixed, with only some sectors experiencing the day-of-the-week effect.     

Transgressing rights: La Via Campesina's call for food sovereignty / Exploring collaborations: Heterodox economics and an economic social rights framework / Workers in the informal sector: Special challenges for economic human rights

Abstract

The notion of rights is a powerful one, but the channels through which they have been promoted and enforced since World War II have militated against the more radical promise of rights. These explorations examine the question of economic rights with an international focus. The contributions touch on such diverse topics as the international peasant federation called La Vía Campesina, heterodox and social economic analyses, and the informal sector. The authors address the question of human rights with respect to the conditions that delimit and enforce these rights, the connections between macroeconomics and human rights, social movements that strive to protect these rights, and the different theoretical approaches to incorporating rights into an academic framework. Though each contribution's methodology and focus are different, the composite takes an important step in evaluating this very critical question of economic rights that greatly affects individual lives, social conditions, economic policies, and the study of economics.
