The limit of law: factors influencing the decision to make harmful acts illegal

Economics of Governance - This paper examines factors affecting the decision of whether or not to make certain harmful acts illegal. It considers factors related both to the cost of law enforcement...     

Causal relationship between construction investment policy and economic growth in Turkey

The construction industry in countries experiencing severe economic crisis has vital importance to get out of stagnation because of its direct relations with 200 different sectors. In this study, the relationship between the construction growth data (infrastructure, building and residential (public), building and residential (private) investment) and gross domestic product (GDP) is examined for Turkey. To this end, Engle–Granger cointegration, error correction model (ECM) and Granger causality tests were applied in order to determine the aforementioned relation. It has been found that the infrastructure and building–residential investments have direct relations with the GDP and have causality effects.     

Verifiability and Contract Enforcement: A Model with Judicial Moral Hazard

I model the litigation of a contract containing a variable notobservable by courts, hence nonverifiable, unless the rationaland self-interested judge exerts effort. He values the correctruling but dislikes effort. Judicial effort is discretionary.I show that effort cost is inconsequential—"always breach"is equilibrium for any effort cost. But there exists anotherequilibrium where a small breach rate is achieved even withsignificant effort costs. Maximal remedies for breach are notoptimal. Because effort is discretionary, low effort cost increasesbreach. Pretrial negotiations can have a substantial negativeimpact on verifiability under arbitrarily small deviations fromfull rationality.     

On the location of public bads: strategy-proofness under two-dimensional single-dipped preferences

In a model with finitely many agents who have single-dipped Euclidean preferences on a polytope in the Euclidean plane, a rule assigns to each profile of reported dips a point of the polytope. A point $x$ of the polytope is called single-best if there is a point $y$ of the polytope such that $x$ is the unique point of the polytope at maximal distance from $y$ . It is proved that if the polytope does not have either exactly two single-best points or exactly four single-best points which form the vertices of a rectangle, then any Pareto optimal and strategy-proof rule is dictatorial. If the polytope has exactly two single-best points, then there are non-dictatorial strategy-proof and Pareto optimal rules, which can be described by committee voting (simple games) between the two single-best points. This also holds if there are exactly four single-best points which form the vertices of a rectangle, but in that case, we limit ourselves to describing an example of such a rule. The framework under consideration models situations where public bads such as garbage dumping grounds or nuclear plants have to be located within a confined region.     

Bribery solicitations and firm performance in the Latin America and Caribbean region

This study shows that for firms in the Latin America and Caribbean region, bribery significantly distorts firm growth. Firms that were solicited for bribes when conducting business transactions – such as applying for permits, electricity, or water connections – have 23% lower annual sales growth than firms that do not face such solicitations. Moreover, these distortions are more severe for low-revenue-generating and young firms. Using the instrumental variables method on cross-sectional data as well as evidence from panel data, the authors show that these results are robust to different specifications and the use of different sub-samples.     

Core is manipulable via segmentation

Any allocation rule that picks only core allocations is manipulable via segmentation. That is, there exists an economy with a coalition of agents such that, once this coalition splits momentarily from the rest of the economy and institutes the allocation rule within itself, no matter which individually rational sub-allocation the complementary coalition picks, when we paste all the agents back together at their new endowments and apply the allocation rule to this “collage” economy, each member of the former coalition will be strictly better off than under direct application of the allocation rule to the original economy.     

The intrinsic fallacy of market mechanism and private property rights in alleviating the tragedy of the commons

ABSTRACT

Economists’ solution to the tragedy of the commons relies on well-defined property rights and competitive market mechanism for limiting individuals’ self-serving, short-sighted actions that result in a dramatic depletion of the common resources. However, this solution implicates a serious threat in terms of sustainability. Recently, deterioration of genetic diversity reached alarming levels, mainly attributed to escalating economic pressure that obliges farmers to shift from local breeds towards more profitable and more productive industrial breeds. This study empirically examines the efficiency of the free market mechanism as a solution to the tragedy of the commons through a unique natural experiment in which a huge demand shock arises regarding sheep. Results robustly show that the free market mechanism can cope with even a very challenging demand shock through the adjustment of prices without any shortage of the commodity. However, this finding does not guarantee that such an outcome is sustainable over the very long term. Analysis of the growth rate of the local sheep breeds population and cross-breed sheep population shows that the trend is overwhelmingly in favour of cross-breeds, thus supporting concerns for a free market mechanism, intrinsically driving the extinction of local sheep breeds, an invaluable genetic resource.     

Determination of the efficiency of the world railway companies by method of DEA and comparison of their efficiency by Tobit analysis

This paper attempts to measure the performance of railway companies that produce passenger and freight services around the world. The data covering 10 years from 2000 to 2009 is analyzed first via the data envelopment analysis method in order to obtain technical efficiency and allocative efficiency scores of 31 railway companies for the purpose of the study. In the analysis conducted by use of the CCR model, while total 17 firms were efficient in the first year, this figure reaches to 18 companies for the last year with one more addition. While only two companies seem efficient in the first year, this figure goes down to one for the last year. With input oriented and variable return analysis conducted by use of the BCC model, the firms having technical efficiency at the beginning of the period were 20 in number. At the end of the period, the figure reaches to 24. Next, the outputs of DEA are correlated by Tobit regression and tried to determine decisiveness of the outputs on the efficiency. It has been seen that the same output composition used with Tobit analysis gives more compliant results with the allocative efficiency scores rather than with the technical efficiency scores.     

Bayesian analysis of the two‐part model with endogeneity: application to health care expenditure

This paper studies the effect of managed care on medical expenditure using a model in which the insurance status is assumed to be endogenous. Insurance plan choice is modeled through the multinomial probit model. The medical expenditure variable, the outcome of interest, has a significant proportion of zeros that are handled using the two‐part model, extended to handle endogenous insurance. The estimation approach is Bayesian, based on the Gibbs Sampler. The model is applied to a sample of 20 460 individuals obtained from the Medical Expenditure Panel Survey. The results provide substantial evidence of selectivity. Copyright © 2006 John Wiley & Sons, Ltd.     

Can progressive taxation account for cross-country variation in labor supply?

The difference between average hours worked in the US and average hours worked in Continental European countries has been increasing since the early 1970s. To explain this phenomenon, this paper develops an endogenous growth model with two key properties: agents are heterogeneous in their rates of time preference and labor skills, and the model incorporates progressive income taxes. The model is calibrated to US and German data for the periods 1971-1974 and 1986-1989. Our findings suggest that the degree of progressivity is a major factor in explaining the patterns of the US and German labor supply over time. Predictions of the model also match the distributional trends in both countries during this time period.
