Game Outcome Uncertainty and Television Audience Demand: New Evidence from German Football

Despite its prominence in the economic literature, our knowledge regarding the role of game outcome uncertainty (GOU) in spectator decision‐making is fairly limited. Even worse, studies testing the uncertainty of outcome hypothesis (UOH) by exploring TV demand for European football have further intensified the original ambiguity. In this paper, we revisit the role of GOU in spectator decision‐making by testing the UOH with regard to two different sporting products: (1) domestic league and (2) knockout tournament games. Analyzing TV demand for almost 1,500 German football games, we find support for the UOH in league, though not in knockout tournament games.

我国银行业市场结构与市场绩效的实证研究

本文运用非参数的数据包络分析法计算我国银行业的X-效率和规模效率,在此基础上对市场结构与市场绩效间的关系进行了实证研究,结果表明在我国银行业市场中"结构-行为-绩效"假说和"有效结构"假说均不成立;作者还进一步从动态的角度,考察了我国银行业市场结构的变化对整体经营绩效的影响,发现"银行内效应"决定了我国银行业绩效变化的方向;但包括市场份额效应、交叉效应和进入效应在内的再配置效应也很重要,特别是行业绩效下降的时期,正的"再配置效应"改善了我国银行业经营的整体业绩,遏制了整体业绩的进一步下降.     

The Chenery hypothesis and structural change in Eastern Europe

The Newly Liberalizing Countries (NLCs) in Eastern Europe have to undergo a fundamental structural change. In this paper the Chenery Hypothesis (CH) is employed to make a quantitative assessment of this change. The CH, roughly speaking, relates an economy's sectoral structure to its stage of development, its size, and its endowment with natural resources. The paper tests this hypothesis for a sample of 31 developed and developing economies and finds it still valid. Then it uses the results obtained to measure distortions in the NLCs' existing economic structure and to give a projection of future structural change. The calculations make it evident that the industrial sector in the NLCs will experience a marked downsizing whilst the service sector turns out to be too small. But sectoral patterns are not too uniform for all groups of countries. Thus, all projections depend highly on the reference group used to evaluate a ‘master pattern’.     

生命成本:关于消费函数理论的一个新假说

消费者行为究竟是收入决定还是成本决定，关系到消费函数理论的基础构建与对诸多重大消费者行为现象的理论解释。传统消费函数理论基于收入假说，忽视了不同消费者为获得同一收入需要付出不同生命成本这一关键事实。由于消费的本质意义在于满足消费者生命的需要，生命为消费付出的代价，才是消费者消费支出的理性尺度。因此，消费者消费支出的决定性影响因子并不是收入差异．而是消费者为获得一定收入付出的生命成本差异。消费者消费倾向差别的根源发生在作为生产者的生产过程，而非消费过程。文章由此提出了基于生命成本假说的消费函数理论，并构建了一个消费者一生产者相统一的消费者行为解释新框架。

Sticky-price models and the natural rate hypothesis

A major criticism of standard specifications of price adjustment in models for monetary policy analysis is that they violate the natural rate hypothesis by allowing output to differ from potential in steady state. In this paper we estimate a dynamic optimizing business cycle model whose price-setting behavior satisfies the natural rate hypothesis. The price-adjustment specifications we consider are the sticky-information specification of Mankiw and Reis (Sticky information versus sticky prices: a proposal to replace the new Keynesian Phillips curve. Quarterly Journal of Economics 117, 1295-1328) and the indexed contracts of Christiano et al. (Nominal rigidities and the dynamic effects of a shock to monetary policy. Journal of Political Economy 113, 1-45). Our empirical estimates of the real side of the economy are similar whichever price adjustment specification is chosen. Consequently, the alternative model specifications deliver similar estimates of the U.S. output gap series, but the empirical behavior of the gap series differs substantially from standard gap estimates.     

Political Fragmentation and the Evolution of National Tax Structures in the OECD

This paper considers how tax structures in OECD countries change over time and how these changes are related to political fragmentation. Tax structures amongst OECD countries have become more uniform in the recent past (1965–1995) but it is less clear that this convergence satisfies time-series requirements. Evidence on stochastic convergence tends to suggest that there is evidence of persistence of shocks remaining over a considerable time period. A consideration of the countries where this persistence is most prevalent shows that there is significant correlation between high persistence and weak (coalition) governments, giving further weight to the theories of weak government.     

Empirical Tests of the Fundamental-Value Hypothesis in Land Markets

The land-price boom of the 1970s followed by the bust of the 1980s generated considerable interest in the determination of land prices and the study of whether those prices reflect fundamental value. In this article, three techniques are used to examine the fundamental-value hypothesis in Iowa and Nebraska agricultural land markets. Duration dependence tests indicate that land markets are not affected by rational expectations bubbles. Conversely, Markov chain and time-reversibility tests suggest that land prices depart from fundamental value due to the existence of nonrandom price changes and asymmetric land price patterns. The results of this research should be viewed as a complement to the existing body of knowledge in our quest to enhance our understanding of agricultural land-price movements.
