Open access,common property and scarcity rent in fisheries

Open access resources are frequently not managed efficiently, resulting in falling stock levels and a declining income for fishermen. In the late 1970's, the policy response to this problem was the implementation of 200-mile fishing zones, which enabled the European Union to formulate and implement the Common Fisheries Policy, aimed at (among other things) conservation and distribution of available stocks. In Germany, this shift from an open access regime towards a common property regime had favourable outcomes. The trend of falling prices was reversed. The conclusion was that intertemporal efficiency had increased as a result of (inter)governmental policy. Apparently, a wedge was formed between price and marginal harvesting costs, implying that scarcity rent had returned as a component of prices.     

Technologies,preferences, and policies for a sustainable use of natural resources

We discuss eight contributions that combine the topics of sustainable natural resource use and economic dynamics. In the first part we consider enhanced oil recovery (EOR), carbon capture and storage (CCS), as well as innovations allowing for energy-efficiency improvements and renewable energy cost reductions. We discuss how to include these technologies and innovations in CGE models, how each of them has different effects on the timing of emissions and abatement and on total emissions, and how (first-best as well as second-best) complementary policies (in particular, emission taxes and innovation subsidies) differ across these technologies. In the second part we compare differences in intergenerational preferences towards resource conservation - altruistic preferences and concern for social status from relative consumption -and also found sharply contrasting effects across the alternative assumptions.

Time,Arbitrage, and the Law of One Price: The Case for a Paradigm Shift

Consider a Competitive, Efficient, and Frictionless Economy (CEFE) where resources are scarce at any date, and hence money as a valid claim against scarce resources is also scarce. In this economy, there is always price competition, which can at any date generate an unlimited number of arbitrage opportunities. For example, at any date, opportunities can exist to buy and sell each one of the contracts for delivery of the same good or asset at multiple prices currently as well as on an infinite number of future dates. I prove all arbitrage transactions, including “spot” transactions, tie up arbitrageurs’ capital representing money, good or asset such that this capital cannot be used for any other purpose for a non-zero quantity of time. This makes it impossible to exploit all arbitrage opportunities with the scarce capital available at any date and leads to an infinite number of unexploited opportunities and a non-negligible opportunity cost of the capital tied-up in arbitrage transactions, represented by each arbitrageur’s best missed arbitrage opportunity, if no better opportunity exits, hence the breakdown of the law of one price in its standard sense. This helps construct a new paradigm of CEFE which resolves long-standing theoretical, empirical, and experimental puzzles.     

Innovation, efficiency, and the quantitative and qualitative demand for human resources

The effects of three kinds of technological changes on employment are considered: (1) basic and major improvement innovations, (2) medium improvement and incremental innovations, and (3) small incremental and pseudoinnovations. The relation between innovation, investment, and employment is studied for the German Democratic Republic (GDR) are the Federal Republic of Germany (FRG). Finally, conclusions are drawn concerning the relation of education or skills to technological stages of industry development.     

Price stickiness, trend inflation, and output dynamics: a cross‐country analysis

Abstract.  Sticky price models based on menu costs predict that countries with high trend inflation should have (i) smaller impact effects of demand shocks on output and (ii) less persistent output fluctuations, relative to low‐trend inflation countries. These predictions are tested, controlling for changes in trend inflation, using a country‐specific approach. The results do not support the second prediction. That prediction is also not robust to a modified measure of trend inflation that excludes episodes of hyperinflation. These findings suggest that while price stickiness is important for understanding short‐run impact effects, real propagation mechanisms may drive persistence in output fluctuations.

大数据、个人信息保护和价格歧视——基于垂直差异化双寡头模型的分析

本文从价格歧视角度出发,讨论大数据时代非敏感个人信息保护的利与弊。传统文献认为,在垄断市场结构下,无个人信息保护会使厂商利用大数据对消费者进行一级价格歧视,从而最小化消费者剩余。本文则证明,一旦引入竞争,消费者总剩余和社会总福利在无个人信息保护和完全一级价格歧视时达到最大,而禁止价格歧视则带来产品的无效分配。此外,不同类型的消费者和厂商对个人信息保护政策的偏好不同。据此,本文认为引入竞争是解决企业利用大数据压榨消费者的有效途径,且消费者的非敏感个人信息应在竞争厂商间公平共享,从而为政策制定者在制定个人信息保护政策时根据行业特点协调各方利益提供了一定的理论依据。     

A Sequential Rationality Test of USDA Preliminary Price Estimates for Selected Program Crops: Rice, Soybeans, and Wheat

Despite recurrent evaluations on USDA price forecasts, the performance of USDA price estimates has not previously been examined in publication. To fill the void in research to this important public information, a sequential forecast evaluation procedure is applied to selected USDA price estimates: Rice, soybeans, and wheat. The evaluation procedure reveals that the USDA price estimates are short-run unbiased; however, they are not long-run rational. In addition, short-run optimality and efficiency tests suggest that USDA price estimates need to be properly scaled and fully reflect information embodied in past prices and their estimates — a possible venue to improve the predictability of USDA price estimates for the crops.     

The effects of economic freedom,regulatory quality and taxation on the level of per capita real income: a preliminary analysis for OECD nations and non-G8 OECD nations

This study of the impact of economic freedom, regulatory quality and the relative burden of taxation on the level of per capita real income/GDP among OECD nations over the period 2003 to 2007 adopts a modified version of the overall economic freedom index computed by the Heritage Foundation (2013), one with the fiscal freedom and business freedom indices removed. This study then provides panel least squares fixed-effects estimates for five linear specifications/models. Each nation during this time frame can be regarded either as a nation per se or as a de facto ‘economic region’ within the OECD. The analysis first focuses upon all of the OECD nations and then, as a robustness test, subsequently focuses only on non-G8 OECD member nations. The estimations in this study all provide strong empirical support for the three central hypotheses proffered here, namely: (1) the higher the overall degree of economic freedom, the higher the per capita real income (GDP) level; (2) the higher the level of regulatory quality, the higher the level of per capita real income (GDP) and (3) the higher the overall tax burden, expressed as a per cent of GDP, the lower is the level of per capita real income (GDP).     

经济分权、人口迁徙与大国发展之路——基于人均产出增长地区差异的实证分析

文章从分权式改革的视角分析了中国改革开放30年来的经济发展道路,总结了中国经济高速增长的主要成功经验在于政治集权下的经济分权。但是经济分权并不能有效缩小城乡、地区与贫富差距,其原因在于中国人口不能自由迁徙,对落后地区的地方政府不能实现“用脚投票”效应,从而影响了对地方政府的监督与激励作用。文章指出只有在人口自由迁徙的条件下,政治集权下的经济分权才能有效激励地方政府,特别是落后地区地方政府发展地方经济的积极性。在认清分权式改革与人口迁徙关系的基础上,正确设计下一步的改革方略,有利于中国真正走出一条大国发展之路。     

Causes of Inflation in Europe, the United States and Japan: Some Lessons for Maintaining Price Stability in the EMU from a Structural VAR Approach

Price stability being among the primary goals of EMU monetary policy,it should be interesting to analyse thefactors that led to the disinflationarydevelopments of the last years. Using a structural VAR approach withlong-run identifying restrictions derived from an open-economy macromodel, various factors of inflation for Austria, Germany, Italy, the UnitedKingdom, the United States and Japan and the extent to which they havecontributed to inflation are analysed. These factors are energy price shocks, supply shocks, wage setting influences, demand and exchange rate disturbances and money supply surprises. The latter three are also used to calculate core inflation. Within a smaller model for aggregate EMU data, supply and demand influences are analysed. While supply and demand factors have generally contributed to the inflation decline, monetary policy, enhanced competition, low energy prices and moderate wage setting are featuring most prominent in the recent disinflation process.

Foreign Aid,Wage Inequality,and Welfare for a Small Open Economy with Tourism

While the welfare effect of foreign aid has been extensively analyzed, the impact on the distribution of income has received less attention. At the same time, there has been recent work on tourism where it is complementary to aid in improving welfare. By combining these two strands, this paper concentrates on wage inequality in developing countries. We find that an increase in aid in the form of tied aid can lower the relative price of nontraded goods. The rent extracted from tourists declines, reducing welfare of domestic residents. In addition, the fall in the nontradable price can widen the wage inequality between skilled and unskilled workers. Thus, increased foreign aid may have detrimental effects on national welfare and the distribution of income. Rising wage inequality is confirmed by numerical simulations.
