Using firm level panel data, we analyze the impacts of rates of return gap between financial and fixed investments under uncertainty on real investment performance in three emerging markets, Argentina, Mexico and Turkey. Employing a portfolio choice model to explain the low fixed investment rates in developing countries during the 1990s, we suggest that rather than investing in irreversible long-term fixed investments, firms may choose to invest in reversible short-term financial investments depending on respective rates of returns and the overall uncertainty in the economy. The empirical results show that increasing rates of return gap and uncertainty have an economically and statistically significant fixed investment reducing effect while the opposite is true with respect to financial investments.  相似文献

This paper analyses the role of risk and rate of time preference in the choice of land contracts. The analysis builds on the risk‐sharing and imperfect market explanations of contract choice. Unique data from Ethiopia, which contain land contract information and experimental risk and rate of time preference measures on matched landlord–tenant partners, are employed in the empirical analysis. The results show that landlord and tenant time preferences are significant determinants of contract choice. For landlords (but not tenants), risk preference is also significant, indicating the importance of financial constraints and production risk in the determination of contract choice. The results are of particular relevance to land market policy in Ethiopia, where production is risk‐prone, financial markets are imperfect, and where there is a major need for the development of vibrant land rental markets.  相似文献

We examine the dynamics of wealth accumulation distribution in Italy using data drawn from the Survey of Household Income and Wealth, a representative survey of the Italian population conducted by the Bank of Italy. We compare survey data with National Accounts data and discuss sample representativeness, attrition and measurement issues. We then look at wealth inequality (the cross‐sectional dispersion of wealth) and wealth mobility (individual transitions across the wealth distribution) and examine the age profile of wealth using repeated cross‐sectional data. Finally, we consider various explanations for the pattern of wealth accumulation in Italy, focusing on retirement, bequests, income risk, health shocks and credit market imperfections.  相似文献

Economic theory has yet to come up with a general guidance regarding the dynamic effects and welfare implications of shocks to public spending. With the aim to provide a theoretical benchmark, we analyse if a rise in private consumption following an exogenous rise in government spending is a feature of the economy under optimal stabilization in a standard New Keynesian setting augmented for the presence of liquidity-constrained agents and non-separable preferences. Our results provide little evidence in support of a crowding-in effect under ‘timelessly optimal’ policy.  相似文献

We examine the role of public debt in financial development. The literature has highlighted its supportive role through providing collateral and benchmark. We contrast this “safe asset” view to a “lazy banks” view: developing banking sectors that lend mainly to the public sector may develop more slowly, because it could make banks profitable but inefficient. Results from country-level and bank-level regressions are more supportive of the “lazy banks” view, but the “safe asset” view seems to play a role at moderate levels of public debt held by banks. There is also evidence of a harmful interaction between public debt and financial repression.  相似文献

Between 1880 and 1930, cooperative insurance was the main source of illness, accident, and death insurance in the United States, Canada, and England. This paper tests for asymmetric information in cooperative insurance societies and examines how their pricing policies affected the profile of members. We find strong evidence that, unlike their modern substitutes, cooperative societies were able to overcome the asymmetry of information. Furthermore, as a consequence of non-actuarial pricing, our results suggest that workers deferred their membership until they were about 40 years old.  相似文献

This paper presents a system cointegration analysis of a long‐run demand for money (measured in terms of M3) in South Africa. In particular, the paper estimates a cointegrated vector autoregression model, consisting of real money, income and the opportunity cost of holding money. Using a variety of theory consistent identification schemes, the money demand function is identified along with other two cointegrating relations, namely, an IS‐type relationship and a relationship relating inflation to the spread between long‐ and short‐term interest rates. The model shows that of the variables used, only income and real money are error‐correcting to the money demand relation. The money demand relation is found to be relatively stable over the sample period, when short‐run fluctuations are corrected for. The model further shows that the long‐run link between money and inflation is rather weak.  相似文献

The main aim of this study is to examine empirically the long‐run relationship of money demand and its determinants in South Africa. In contrast with existing studies on the subject, the present study considers various components of real income as determinants. The disaggregated components are final consumption expenditure, expenditure on investment goods and exports. The other determinants are domestic interest rate, yield on government bonds and the exchange rate. The results confirm that the different components of real income have different impacts on the demand for money in South Africa. The presence of long‐run equilibrium relationships between the demand for real M1, M2 and M3 and their determinants is confirmed based on the results of bounds testing.  相似文献

What modern game theorists describe as “fictitious play” is not the learning process George W. Brown defined in his 1951 paper. Brown's original version differs in a subtle detail, namely the order of belief updating. In this note we revive Brown's original fictitious play process and demonstrate that this seemingly innocent detail allows for an extremely simple and intuitive proof of convergence in an interesting and large class of games: nondegenerate ordinal potential games.  相似文献

This paper studies the impact of migration policy liberalisation on international labour migration in the enlarged European Union (EU) in a structural economic geography approach. The liberalisation of migration policy would induce an additional 1.80–2.98% of the total EU workforce to change their country of location, with most of migrant workers relocating from the East to the West. The average net migration rate is decreasing in the level of integration, suggesting that from an economic point of view no regulatory policy responses are necessary to labour migration in the enlarged EU.  相似文献
