Economic Efficiency Requires Interaction

We study the necessity of interaction between individuals for obtaining approximately efficient allocations. The role of interaction in markets has received significant attention in economic thinking, e.g. in Hayek's 1945 classic paper. We consider this problem in the framework of simultaneous communication complexity. We analyze the amount of simultaneous communication required for achieving an approximately efficient allocation. In particular, we consider two settings: combinatorial auctions with unit demand bidders (bipartite matching) and combinatorial auctions with subadditive bidders. For both settings we first show that non-interactive systems have enormous communication costs relative to interactive ones. On the other hand, we show that limited interaction enables us to find approximately efficient allocations

Analysis Of Economic Efficiency Of Grain Production Of Main Food And Grain-forage Crops In The Region

The estimation of the economic efficiency of agrarian enterprises is based on the use of the system of interconnected indices of natural and valuable calculation that reflect the effect and influence forms of objective economic laws in material production of agrarian sphere taking into account its peculiarities. In the process of the study of the economic efficiency of grain production of main food and grain-forage crops in the studied region we have considered a series of main production-financial parameters that are determined by their nature as: a ratio between resources consumption and volume of goods and services, produced of these resources; maximal volume of production of goods and services using the minimal cost of resources; obtaining of the maximal result of limited resources, accessible for a human. The essential increase of grain production and improvement of its economic efficiency is, undoubtedly, the most important task of the state agrarian policy, its solution determines guaranteeing of the effective activity of both grain-production subcomplex and agro-industry in whole and also food safety of the country. The scientific article presents the analysis of the economic efficiency of grain production on the example of agrarian enterprises of Ternopil region in 2010-2016. The work demonstrates economic-financial results of realization of grain and leguminous crops of the region and also presents production-economic indices of realization of grain of main food and grain-forage crops – wheat, corn for grain, barley, buckwheat, pea. The realized work allows to determine tendencies of the economic efficiency of grain production, to estimate its competitiveness under conditions of the market environment

Taxes, Efficiency and Economic Growth

In the third paper on taxation, Jack M. Mintz and Thomas A. Wilson consider the best way to allocate the “fiscal dividend”. This is the amount available to the government that can be used for tax cuts or expenditure increases within the framework of a balanced budget. In their view, although the current growth recession will reduce the potential surplus somewhat, the medium-term outlook is still for increasing surpluses. Concerned about lagging economic growth and emphasizing the importance of efficiency and productivity growth, they argue that priority should be given to debt reduction and tax cuts designed to stimulate investment and potential growth. Mintz and Wilson make the case that a large part of the remaining fiscal dividend should be allocated towards reducing the relatively large personal income tax burden faced by many Canadian families and individuals. But they also stress that it is important to steadily reduce payroll and business taxes as well. This case is supported by extensive international comparisons of taxes in Canada with other countries that show that the burden of taxation is higher in Canada than in many other industrialized countries. It is also bolstered by the results of simulations, using the FOCUS macroeconometric model, of a fiscal package containing significant debt reduction, modest spending increases and cuts in personal, business and payroll taxes. These simulations show such a fiscal package should have favourable supply-side effects on output, employment and productivity over the medium term. In addition, since their analysis reveals that there are still important issues of tax structure that need to be addressed, they recommend that the government establish a task force to review personal income taxes and to consider the need for additional tax cuts. Finally, Mintz and Wilson also remind us that while planned debt reduction is an important component of a growth-oriented fiscal policy, in the short run the size of the surplus should be allowed to vary with the level of economic activity. Otherwise fiscal policy will exacerbate the slowdown that is currently underway.FOCUS, Taxation, Simulation, Forecast, Efficiency, Growth, Debt Reduction

Contingent trade policy and economic efficiency

This paper develops an efficiency theory of contingent trade policies. We model the competition for a domestic market between one domestic and one foreign firm as a pricing game under incomplete information about production costs. The cost distributions are asymmetric because the foreign firm has to pay a trade cost. We show that the foreign firm prices more aggressively to overcome its cost disadvantage. The resulting possibility of an inefficient allocation justifies the use of contingent trade policy on efficiency grounds. Contingent trade policy that seeks to maximize global welfare can avoid the potential inefficiency. National governments, on the other hand, make excessive use of contingent trade policy due to rent shifting motives. The expected inefficiency of national policy is larger (smaller) for low (high) trade costs compared to the laissez-faire case. In general, there is no clear ranking between the laissez-faire outcome and a contingent national trade policy.

Banking Permits: Economic Efficiency and Distributional Effects

Most analyses of the Kyoto flexibility mechanisms focus on the cost effectiveness of “where” flexibility (e.g. by showing that mitigation costs are lower in a global permit market than in regional markets or in permit markets confined to Annex 1 countries). Less attention has been devoted to “when” flexibility, i.e. to the benefits of allowing emission permit traders to bank their permits for future use. In the model presented in this paper, banking of carbon allowances in a global permit market is fully endogenised, i.e. agents may decide to bank permits by taking into account their present and future needs and the present and future decisions of all the other agents. It is therefore possible to identify under what conditions traders find it optimal to bank permits, when banking is socially optimal, and what are the implications for present and future permit prices. We can also explain why the equilibrium rate of growth of permit prices is likely to be larger than the equilibrium interest rate. Most importantly, this paper analyses the efficiency and distributional consequences of allowing markets to optimally allocate emission permits across regions and over time. The welfare and distributional effects of an optimal intertemporal emission trading scheme are assessed for different initial allocation rules. Finally, the impact of banking on carbon emissions, technological progress, and optimal investment decisions is quantified and the incentives that banking provides to accelerate technological innovation and diffusion are also discussed. Among the many results, we show that not only does banking reduce abatement costs, but it also increases the amount of GHG emissions abated in the short-term. It should therefore belong to all emission trading schemes under construction.emission trading, banking

Banking efficiency and economic growth in the MENA region

This paper examines the nexus between cost efficiency and economic growth in the Middle East and North Africa region. We apply a causality analysis between cost efficiency and financial deepening using the Generalized Methods of Moments and our findings show a significant and positive causality and reverse relationship between financial deepening and banking productivity. We introduce a set of control variables associated with the long run growth and find an interesting interaction with banking productivity and financial deepening suggesting that efforts should be focusing on the investments’ efficiency and the increase of regulation to spur a more stable financial system and foster financial deepening in the future
