A welfare analysis of social security in a dynastic framework*

In this article, we study the welfare effects of unfunded social security in a general equilibrium model populated with overlapping generations of altruistic individuals that differ in lifetime expectancy and earnings ability. Contrary to previous research, our results indicate that steady‐state welfare increases with social security for most households, although by very different amounts. This result is mainly due to two factors. First, the presence of two‐sided altruism significantly mitigates the crowding out effect of unfunded social security. Second, ability shocks and uncertain lifetimes generate significant heterogeneity among households to yield different induced preferences for social security.     

The Brand Choice Model of Wine Consumers: A Multinomial Logit Model

The objective of this study is to determine factors influencing brand preferences of wine consumers in the Marmara region where viniculture and wine production is so important in Turkey. First, the consumers’ preferences survey has been conducted with 1022 persons in the region randomly selected and evaluated. Then, the informative factors influencing brand preferences collected in these surveys have been determined by the multinomial logit model. A lot of independent variables have been used in the multinomial logit model, but, because some independent variables were not found as significant according to Likelihood Ratio test, these variables are not included in the multinomial logit analysis. Six important factors influencing wine brand preferences have been determined. These factors are brand change causes of consumers, occupation of consumers, marital status of consumers, birthplace of consumers, income of consumers and gender of consumers. In addition, whether the wine brand preferences are independent, has been tested with Testing Independence of Irrelevant Alternatives of Hausman. According to this test, it has been found that the wine brand preferences are independent.     

Contagion Effects from the 1994 Mexican Peso Crisis: Evidence from Chilean Stocks

The contagion, or informational spillover, effects of the 1994 peso crisis from the Mexican market to the Chilean market, and to the Chilean American Depository Receipts (ADRs) trading in the U.S., are examined. Significant excess returns are observed for Chilean stocks for the event dates of the Mexican Peso crisis, providing evidence of contagion effects. Significant excess returns on these Chilean ADRs are also observed for each of the five event dates associated with the Peso crisis, suggesting that the contagion effects spilled over to the ADRs. A multiple regression model shows that the spillover contagion effects were very efficiently transmitted from the Mexican market to the Chilean market to the Chilean ADRs. Multifactor regressions show that the most significant influence on the pricing of Chilean ADRs is the raw Chilean Index, rather than the Chilean Index expressed in U.S. dollars.     

Engines of Growth in China: The Limits of Informal Institutions

Abstract:

Since the 1978 reforms, China has experienced rapid economic and social development. GDP growth has been in the double digits on average yearly, creating the fastest sustained economic growth recorded by a major economy in history. Not only did this transform the economy and society at large, China reached important milestones in terms of reducing poverty and creating prosperity in a short period of time. This article uses the conceptual framework of new institutional economics to examine China’s economic growth and how growth has been achieved largely by ‘informal institutions’ that are grounded in culture, customs, and private interactions that emerge spontaneously. The trajectory by which these informal institutions left their imprint on China’s complex economic landscape and how they can constrain future economic growth are also of central importance. After examining decentralization and risk management practices, property rights, and the legal system, we emphasize the importance of creating formal institutions necessary for long-term growth, most importantly innovation. Preliminary evidence shows total factor productivity is tapering off which may reflect the constraints of China’s institutional environment. This ought to be reversed if China is to enjoy long-term sustained growth.     

Optimal monetary policy regime for oil producing developing economies: Implications for post-war Iraq

This paper theoretically investigates optimal monetary policy regime for oil producing developing countries. We analyze credibility and reputation of the Central Bank and macroeconomic dynamics under alternative monetary policy regimes. We construct a detailed and realistic model that can be used to analyze macroecomic structure and expectation dynamics of an oil producing open economy. We take into account the asymmetric information between the public and the central bank and theoretically investigate how this asymmetric information impacts the real economy and the credibility of the central bank. The simulation results indicate that central bank achieves higher credibility and lower inflation under dollarization and higher output levels under currency board regime. The model constructed in this paper has many policy implications for oil producing open economies. Using the implications of the model, we make monetary policy regime recommendations for post-war Iraq.     

The Behavior of the Real Exchange Rate Under Fixed and Floating Exchange Rate Regimes

This article investigates the behavior of real exchange rates under fixed and flexible exchange rates. Using data from both the Bretton Woods and the modern floating periods, we decompose real exchange rate movements into components attributable to supply shocks, real demand shocks, monetary shocks, capital flows shocks, and real oil price shocks. Empirical results show that real demand shocks are an important source of real exchange rate movements under both fixed and flexible rates, while monetary shocks are negligible. Supply and oil price shocks seem to be more important under Bretton Woods, while capital flows shocks seem to explain a relatively higher proportion of real exchange rate movements under the modern floating period.     

A direct test of the endogeneity of money: Implications for Gulf Cooperation Council (GCC) countries

This paper contributes to the ongoing discussion about the endogeneity of money supply by empirically investigating the GCC countries. We propose and implement a direct test of money supply endogeneity that depends on econometric specification of exogeneity which has not been used in the literature before. To be able to make comparisons with previous studies, we also conducted Granger Causality tests to analyze the causality relationship between bank credit and money supply. Both of the empirical studies provide empirical evidence for the endogeneity of money supply in GCC countries. The results of the paper have many significant monetary policy implications for the upcoming monetary unification of the GCC countries.     

Choosing the share bond by using qualitative dependent variable models in Turkey

In this paper whether the bond according to a certain criterion for one time period in the future with the classic logit models and for a certain time period in the future with the panel logit model is successful or not have been forecasted. For this purpose financial ratios of the industrial companies listed on Istanbul Stock Exchange in Turkey over the period 1995–2001 were used. The results indicated that different financial data is effective in the different models used for different terms i.e., the models are different for each other.
