Housing price-to-income and price-to-rent ratios are among the most widely monitored indicators of housing market conditions. While these ratios tend to fluctuate around a constant level or a mild trend over the long term, they also tend to deviate from these benchmarks for protracted periods. Traditional unit root tests often indicate the presence of a unit root. This article uses the framework of fractional integration to test the persistence of price-to-income and price-to-rent ratios in a sample of 16 OECD countries spanning four decades. The results indicate that the ratios are highly persistent. The possibility that persistence estimates may be affected by structural breaks in the series is also considered, but evidence of such breaks is found only in a very limited number of cases. Policy action may be required if high price-to-income and price-to-rent ratios have adverse social and economic consequences. Policies should be guided by a careful analysis of the factors behind high ratios. 相似文献

In this paper we focus on the determinants of internationalization and, in particular, on the specific role played by the agglomeration of small and medium sized enterprises (SMEs) through their proximity to a large firm. We study the characteristics of the internationalization process in a representative sample of 786 firms in the Italian automotive supply chain. After building an Internationalization Strategy Index (ISI), we perform a multinomial logit econometric analysis. The main findings of the empirical analysis are: (a) Italian automotive supplier firms mainly go in the foreign markets through export, i.e. the simplest internationalization mode; (b) as predicted in the literature, individual firm characteristics play a significant role in the probability of internationalization; (c) firms located in the province of Turin, where the dominant car assembler (Fiat) in Italy has its headquarters, or more generally, in large automotive industry districts, enjoy a clear localization advantage; (d) interestingly, we also find that internationalization is negatively correlated with the share of Fiat in suppliers’ sales, and that suppliers located in a district and less dependent on Fiat are also those adopting the most advanced internationalization strategies. 相似文献

Rising household debt: Its causes and macroeconomic implications--a long-period analysis 总被引:1,自引:0,他引:1
The article analyses the rise in household indebtedness fromthe point of view of its causes and long-run macroeconomic implications.The analysis is focussed on the US case. Differently from life-cycleinterpretations of the phenomenon, and from interpretationsin terms of erratic deviations of current income flows fromtheir long-run trend, the rising household debt is viewed asthe outcome of persistent changes in income distribution andgrowing income inequalities. Through household debt, low wagesappear to have been brought to coexist with relatively highlevels of aggregate demand, thus providing the solution to thecontradiction between the necessity of high and rising consumptionlevels, for the growth of the system's actual output, and aframework of antagonistic conditions of distribution which keepswithin limits the real income of the vast majority of society.The question of the long-run sustainability of this substitutionof loans for wages is finally discussed. 相似文献

PORTFOLIO SELECTION WITH MONOTONE MEAN-VARIANCE PREFERENCES 总被引:2,自引:0,他引:2
Fabio Maccheroni Massimo Marinacci Aldo Rustichini Marco Taboga 《Mathematical Finance》2009,19(3):487-521
We propose a portfolio selection model based on a class of monotone preferences that coincide with mean-variance preferences on their domain of monotonicity, but differ where mean-variance preferences fail to be monotone and are therefore not economically meaningful. The functional associated with this new class of preferences is the best approximation of the mean-variance functional among those which are monotonic. We solve the portfolio selection problem and we derive a monotone version of the capital asset pricing model (CAPM), which has two main features: (i) it is, unlike the standard CAPM model, arbitrage free, (ii) it has empirically testable CAPM-like relations. The monotone CAPM has thus a sounder theoretical foundation than the standard CAPM and a comparable empirical tractability. 相似文献

ABSTRACT ** : This paper analyzes the demand of Swiss families for child care facilities. A choice experiment is used to study the effects of the facilities' characteristics as well as socio-economic factors on the selected child care mode. The experimental data are analyzed using a discrete choice model with multinomial logit specification. The results suggest that the demand for extra-familial day care could be considerably higher than that observed from the actual choices constrained by insufficient provision of affordable day care. The price, access, and the quality of service as well as parents' income and education have important impacts on the choice of the mode of care. 相似文献

This paper studies a model whereby exclusive dealing (ED) can both promote investment and foreclose a more efficient supplier. Since ED promotes the incumbent seller's investment, the seller and the buyer realize a greater surplus from bilateral trade under exclusivity. Hence, the parties involved may sign an ED contract that excludes a more efficient entrant in circumstances where ED would not arise absent investment. The paper therefore invites a more cautious attitude towards accepting possible investment promotion arguments as a defense for ED. 相似文献

Abstract. This paper deals with the determinants of agents' acquisition of information. Our econometric evidence shows that the general index of Italian share‐prices and the series of Italy's financial newspaper sales are cointegrated, and the former series Granger‐causes the latter, thereby giving support to the cognitive dissonance hypothesis: (non‐professional) agents tend to buy the newspaper when share prices are high and not to buy it when share prices are low. Instead, we do not find support for the hypothesis that the agents acquire information in order to trade in the stock market: we find no relationship between quantities exchanged in the market and newspaper sales, nor between stock market volatility and newspaper sales. 相似文献

Welfare gains to long-horizon investors may derive from time diversification that exploits nonzero intertemporal return correlations associated with predictable returns. Real estate may thus become more desirable if its returns are negatively serially correlated. While it could be important for long-horizon investors, time diversification has been mostly investigated in asset menus without real estate and focusing on in-sample experiments. This article evaluates, ex post, the out-of-sample gains from diversification when equity real estate investment trusts (REITs) belong to the investment opportunity set. We find that diversification into REITs increases both the Sharpe ratio and the certainty equivalent of wealth for all investment horizons and for both classical and Bayesian (who account for parameter uncertainty) investors. The increases in Sharpe ratios are often statistically significant. However, the out-of-sample average Sharpe ratio and realized expected utility of long-horizon portfolios are frequently lower than that of a one-period portfolio, which casts doubt on the value of time diversification. 相似文献

This paper analyzes the empirical performance of two alternative ways in which multi-factor models with time-varying risk exposures and premia may be estimated. The first method echoes the seminal two-pass approach introduced by Fama and MacBeth (1973). The second approach is based on a Bayesian latent mixture model with breaks in risk exposures and idiosyncratic volatility. Our application to monthly, 1980–2010 U.S. data on stock, bond, and publicly traded real estate returns shows that the classical, two-stage approach that relies on a nonparametric, rolling window estimation of time-varying betas yields results that are unreasonable. There is evidence that most portfolios of stocks, bonds, and REITs have been grossly over-priced. On the contrary, the Bayesian approach yields sensible results and a few factor risk premia are precisely estimated with a plausible sign. Predictive log-likelihood scores indicate that discrete breaks in both risk exposures and variances are required to fit the data. 相似文献
