Policy commitment and the welfare gains from capital market liberalization

This paper evaluates the quantitative impact of capital liberalization on the taxation structure and welfare of the liberalizing countries when governments conduct fiscal policy optimally but without commitment (time-consistent policies). The transition from a regime of capital autarky to a regime of free mobility leads to a decrease in the long-term tax rate on capital of 13 percent and an increase in the tax rate on labor of 2 percent. As a consequence of this taxation shift, welfare increases by about 1 percent. The reduction in capital taxation induced by capital market liberalization is welfare improving because, in the absence of capital mobility, the time-consistent policies over-tax capital.     

External factors in emerging market recoveries: An empirical investigation

We estimate conditional duration models to analyse recovery processes in emerging market economies. Our reduced form specification is parsimonious, as we focus on exogenous factors, such as the effect of growth in the US, EU, and Japan on the prospects for recovery in emerging market economies experiencing recessions. The model confirms the importance of external factors in recovery processes. However, the short-run effect of Japanese growth on recovery prospects is unconventional: weak economic conditions in Japan turn out to facilitate recoveries.

Energy substitutability in transition agriculture: estimates and implications for Hungary

Subsidised energy prices in pre‐transition Hungary had led to excessive energy intensity in the agricultural sector. Transition has resulted in steep input price increases. In this study, Allen and Morishima elasticities of substitution are estimated to study the effects of these price changes on energy use, chemical input use, capital formation and employment. Panel data methods, Generalised Method of Moments (GMM) and instrument exogeneity tests are used to specify and estimate technology and substitution elasticities. Results indicate that indirect price policy may be effective in controlling energy consumption. The sustained increases in energy and chemical input prices have worked together to restrict energy and chemical input use, and the substitutability between energy, capital and labour has prevented the capital shrinkage and agricultural unemployment situations from being worse. The Hungarian push towards lower energy intensity may be best pursued through sustained energy price increases rather than capital subsidies.     

The effects of trust and land administration on economic outcomes: Evidence from Vietnam

This paper examines how the interaction of social trust and institutions, such as land administration, affects household economic decisions in Viet Nam. Using a panel dataset of rural households from 2008 to 2014, we show that negative consequences of the duration of land administration on agricultural investment have been lower in rural households with higher level of trust. Higher-trust households, when facing higher barrier from land administration, tend to invest more on agricultural land compared to low-trust households where household heads are male. We also find that high-trust households enhance land property rights when facing obstacles from land administration.

Empirical labor search: A survey

This paper surveys the existing empirical research that uses search theory to empirically analyze labor supply questions in a structural framework, using data on individual labor market transitions and durations, wages, and individual characteristics. The starting points of the literature are the Mincerian earnings function, Heckman's classic selection model, and dynamic optimization theory. We develop a general framework for the labor market where the search for a job involves dynamic decision making under uncertainty. It can be specialized to be in agreement with most published research using labor search models. We discuss estimation, policy evaluation with the estimated model, equilibrium model versions, and the decomposition of wage variation into factors due to heterogeneity of various model determinants as well as search frictions themselves. We summarize the main empirical conclusions.

Insurance market mechanisms and government interventions

The expansion of the State-as-insurer has played a major role in the long-term growth of the public sector, but we are probably reaching the turning point. Because of its manifold failures, the State-as-insurer is facing crisis all around the world, with exploding expenditures. This will probably induce a shift in the private–public frontier, which makes it much more important than in the past to regulate the insurance industry efficiently. Coming back to the failures of the State-as-insurer, we should underline the role played by this flawed hypothesis that sets market logic and private interest against public interest.
