Reexamining the permanent income hypothesis with uncertainty in permanent and transitory innovation states

In this paper, we reexamine the permanent income–consumption relationship analytically and empirically, based on the innovation regime-switching (IRS) model developed in [Kuan, C.M., Huang, Y.L., Tsay, R.S., 2005. An unobserved component model with switching permanent and transitory innovations. Journal of Business and Economic Statistics, 23, 443–454]. A novel feature of the IRS model is that it explicitly allows for uncertainty in innovation states. When the labor income follows an IRS process, it is shown that the agent’s perception on the likelihoods of income innovations being permanent and transitory plays a crucial role in determining the optimal forecasts on the change of consumption. The effect of a current labor income innovation on consumption is a weighted average of two distinct effects resulting from permanent and transitory innovations with the weights equal to the perceived likelihoods of the respective states. Also, past innovations may affect consumption when there are revisions in the perceived likelihoods of previous states. Our empirical study on US data shows that consumption indeed reacts significantly to the perceived likelihoods of innovation states. However, even after controlling for the effect of state uncertainty, we find consumption vastly underreacts to permanent innovations in labor income but reacts about the right magnitude to transitory ones when compared with the prediction of the permanent income hypothesis. This evidence is similar to [Elwood, S.K., 1998. Testing for excess sensitivity in consumption: A state-space unobserved components approach. Journal of Money, Credit, and Banking, 30, 64–82] but in sharp contrast with that found in [Hall, R.E., Mishkin, F.S., 1982. The sensitivity of consumption to transitory income: Estimates from panel data on households. Econometrica, 50, 461–480].     

The permanent income hypothesis: A new framework based on fractional integration and cointegration

The issue of the Permanent Income Hypothesis (PIH) is revisited in this paper by examining the relationship between U.S. consumption and income through new statistical techniques based on fractional integration and cointegration. Using a procedure by Robinson [1994a] that permits the testing of I(d) statistical models, the results show that both individual series are I(1). However, the differences seem to be I(d), with d being smaller than 1 in some cases. Also, when performing different regressions of consumption on income, the estimated residuals from the cointegrating regressions appear to be mean reverting. This implies that consumption and income may be fractionally cointegrated, so that deviations from equilibrium are highly persistent. Thus, the results provide further evidence regarding the validity of the PIH for the U.S.The author gratefully acknowledges the comments from an anonymous referee.

Inflation targeting in emerging economies: Panel evidence

This paper shows there is no evidence that the inflation targeting regime (IT) improves economic performance as measured by the behavior of inflation and output growth in developing countries. The control of common time effects results in less negative and less significant IT impacts on inflation, inflation volatility and output growth volatility than previously found in the literature. Additionally, our analysis shows robust evidence of lower output growth during IT adoption. On balance, although lower long-run mean inflation signals that the central banks of emerging economies with inflation targeting are more inflation-averse, the costs of disinflation have not been lower than under other monetary regimes.     

The Ricardian equivalence hypothesis: evidence from Bangladesh

In this paper, a probabilistic discrete choice approach is used to examine the influence of economic and non-economic factors on the choice of medical specialty by new physicians. A two level nested logit model is estimated that relaxes the independence from irrelevant alternatives assumption, and allows for a potentially more realistic pattern of substitution across specialty choices. The results from this specification are compared to those obtained from joint and conditional logit models. The findings, which are relatively robust across models, indicate that economic incentives play an important role in the specialty choice process, in particular, expected hours worked and medical school indebtedness. Physician tastes for specialties also appear to have an important influence.     

Male-female wage differentials: Additional evidence

By applying a richer data set than others have used to a simultaneous equation regression model, the analysis sheds new light on the existence and magnitude of the male-female wage differential.     

Satisfaction and comparison income in transition and developed economies

The main purpose of this paper is to evaluate the impact of different types of income comparison on subjective well-being in transition countries and developed European countries. The paper relies on the Life in Transition Survey (European Bank for Reconstruction and Development 2011), which was conducted in late 2010 jointly by the European Bank for Reconstruction and Development and the World Bank. The emphasis of the paper is on income comparisons, specifically; local comparisons and self-ranking. The main findings reveal that comparisons have a significant impact on life satisfaction in transition countries, whereas the relationship between comparison and life satisfaction is ambiguous in developed European countries. In transition countries, the impact of comparisons is asymmetric: in most cases, under-performing one’s benchmark has a greater effect than out-performing it. In transition countries, both downward and upward evaluations have an impact on life satisfaction, while it is worthy of note that all upward evaluations have no effect on life satisfaction in developed European countries.     

The absolute health income hypothesis revisited: a semiparametric quantile regression approach

This paper uses the 1998–1999 Canadian National Population Health Survey data to examine the health–income relationship that underlies the absolute income hypothesis. To allow for nonlinearity and data heterogeneity, we use a partially linear semiparametric quantile regression model. The “absolute income hypothesis” is partially true; the negative aging effects appear more pronounced for the ill-healthy population than for the healthy population and when annual income is below 40,000 Canadian dollars.

The interchangeability of alternative measures of permanent income in regression analysis

Recent years have witnessed a sharp rise in crime levels in most of the societies across the world. Apart from the increasing direct costs involved in the containment/control of crime, the subject societies also bear considerable psychic costs (results of fear of crime or the after effects of crime). These costs of crime are perceived to be higher in developing economies. Economists consider crime to be rational behaviour under specific scenarios is sparse. In this paper, we characterize the rising-crime scenarios in terms of several demographic and economic variables. Regression models relating different types of crime to these societal variables are fitted, using crime data from Malaysia (from published records of the Government of Malaysia). The model fit is found to be extremely good with most of these observational data.     

Trade adjustment policies and income distribution in three archetype developing economies

This paper explores quantitatively the macroeconomic and distributional impacts on non-oil producing, semi-industrial developing countries of external shocks originating in the world economy —in particular, rising costs of imports and shrinking export markets. The empirical analysis is done with a computable general equilibrium (CGE) model. The effects of the same external shock are modelled for three different archetype economies: a primary exporter, a manufacturing exporter, and a closed economy. Three different policy-adjustment regimes are considered: devaluation, premium rationing of imports (import licenses), and premium rationing in an environment with a fixed real wage for unskilled labor. By making simple assumptions about the way socioeconomic groups operate to influence decision-making, the paper also examines how the struggle between the gainers and losers is likely to affect the policy regime to be chosen.     

The relative importance of capital inflows: some evidence from emerging market economies

This article examines the relative importance of the main components of capital inflows for a sample of emerging market economies. Does composition matter? Is there a nexus between capital inflow components? We assess, firstly, how each capital inflow component reacts to important macro and policy variables, and secondly, how the components themselves interact. We find that bank inflows appear the most sensitive to macro factors, institutions matter more for Latin America and external financial factors matter more for Asia. Further, for Latin America, capital inflows interact largely as complements, while for Asia, any expansion of bank inflows might crowd out FDI and portfolio flows.     

Corporate governance and efficiency in banking: evidence from emerging economies

ABSTRACT

This article investigates the impact of corporate governance on bank efficiency across a sample of 139 commercial banks from 17 countries of Central and Eastern Europe during the period 2005–2012. Data on governance characteristics are hand-collected from banks’ reports. The empirical findings indicate that implementing rigorous corporate governance structures is associated with higher costs for banks and a lower level of efficiency. However, during the crisis, a tight governance mechanism significantly increases banks’ cost and technical efficiencies. We also show that prudent risk management is associated with both higher cost and technical efficiency for more capitalized banks, while rigid supervisory boards are linked with greater technical efficiency for more capitalized banks.     

Economic reforms and human development: evidence from transition economies

Do market-oriented economic reforms result in higher levels of human well-being? This article studies the impact of macro-level institutional and infrastructure reforms on the economic, educational and health dimensions of human well-being among 25 transition economies. We use panel data econometrics based on the LSDVC technique to analyse the effects of market-oriented reforms on the human development index (HDI), as a measure of human well-being, from 1992 to 2007. The results show the complexity of reform impacts in transition countries. They show that institutional and economic reforms led to positive economic effect and significant impacts on other dimensions of human development. We find some positive economic impacts from infrastructure sectors reforms. However, not every reform measure appears to generate positive impacts. Large-scale privatizations show negative effects in health and economic outcomes. The overall results show the importance of the interaction among different reform measures and the combined effect of these on human development.     

Firm productivity and agglomeration economies: evidence from Egyptian data

This paper attempts to shed the light on the nexus between firms’ productivity and economies of agglomeration in Egypt. Using a large dataset of firms in 342 firms’ four-digit activities in 27 regions (62,108 firms), we introduce three measures of agglomeration which are urbanization or firm diversification measured by the number of firms by governorate, localization and specialization measured by the average productivity by governorate and sector (generating externalities and knowledge spillovers) and finally competition measured by the number of firm operating in the same governorate and the same sector. We find strong evidence for the existence of agglomeration in Egypt after controlling for firm age, location, economic activity and legal status. In the Egyptian context, productivity spillovers gained from agglomeration measures outweighed the negative effects of competition implied by congestion. The latter is chiefly due to the lack of good infrastructure. When regressions are run by firm size, location and activity, our main findings show first that micro and small firms are more likely to benefit from localization and diversification compared to medium and large firms. Service firms benefit more from high level of diversification while manufacturing firms gain more benefits from knowledge spillovers and specialization in Egypt.     

The structure of income mobility: empirical evidence from five UE countries

In this paper we use the European Community Household Panel (ECHP) to assess differences in the level and structure of income mobility in a selected sample of European countries. We adopt recent theoretical proposals for the decomposition of axiomatic and welfare measurements of mobility in exchange, structural and growth components. Decomposition exercises which take into account some type of division of the population and income sources are also performed. We find that cross-country income mobility comparisons largely depend on the type of indices used. The relative positions of the countries considered change when the analysis is based on ethical instead of objective measures of income mobility. Results also show that in most countries income growth has a very limited effect upon aggregate mobility, being the most important determinant the rerankings of individuals, with a little weight for inequality changes. Although some common results exist concerning the delimitation of groups experiencing the greatest income fluctuations, such as individuals belonging to single-parent households or young household heads, the intensity of these results varies greatly across countries.

The real effect of currency misalignment on productivity growth: evidence from middle-income economies

There have been interesting perspectives on the role of real currency misalignment in productivity growth. Whereas some studies warn against the destructive effect of real currency misalignment on productivity growth, others simply encourage it, at least, in the form of undervaluation. This paper documents evidence in support of the latter argument for 100 middle-income countries for the 1994–2010 period, using fixed-effects and generalized method of moments estimation techniques. The paper finds real currency misalignment to enhance productivity growth if it occurs as undervaluation; and to hamper productivity growth if it occurs as overvaluation. The paper also finds the impact of real currency misalignment on productivity growth to be symmetric, implying that the size of the impact is independent of the size of the misalignment. Moreover, the choice of the real misalignment measure may matter.
