我国水资源严重短缺的基本国情使农村的供水与用水的矛盾越来越突出,加上城市和工业对水的需求日益扩大,农业水权的转让逐渐成为一种趋势。在农业水权转让的过程中,农民用水权益的保护成为了亟须重视的问题。目前我国农业水权转让制度不健全,使农业水权在向其他领域转让过程中出现了损害农民用水权益的现象。因而,分析农业水权在转让过程中对农民用水权益的影响因素,从而提出保护对策,为完善农民用水权益保障机制提供基础。     

An empirical investigation of causality between producers' price and consumers' price indices in Australia in frequency domain

The paper examines Granger-causality between the producers' and the consumers' price using Australian data within the frequency domain framework. For long run relation, the Johansen and Juselius (1990) maximum likelihood approach to cointegration was utilized. The test is also supplemented by the Breitung and Candelon (2006) and Lemmens et al. (2008) method. The quarterly data for the study covers 1969q3 to 2010q4. The findings suggest that consumers' price Granger-causes producers' price at an intermediate level of frequencies reflecting medium-run cycles, whereas producers' price does not Granger-cause consumers' price at any level of frequencies. Our study shows that consumers' price is a leading indicator of producers' price. Given that producers' price is used in making various macroeconomic indicators in real terms, the findings should help the Australian policymakers to gain control over the factors that affect consumers' price. The major contribution of the paper is to demonstrate unidirectional causality from consumers' price to the producers' price. Specifically, results show that consumers' price in Australian may have a significant predictive content in how the producers' price evolve. Furthermore, the application of the Breitung and Candelon (2006) and Lemmens et al. (2008) methodology in testing the Granger-causality in frequency domain is also relatively new.     

An empirical study of world market influences on price formation in West Germany

In this paper price and wage determination is analyzed for 35 industries in West-Germany. Tests are made to classify industries as being competitive, discriminatory or sheltered. The chosen approach is related to the “Scandinavian” model. It is shown that about a third of the industries in the sample are not price takers in spite of international trade. Wages are strongly influenced by world market and exchange rate developments. As to the effectiveness of revaluations the results imply that, first, revaluations do provide a protection against imported inflation. Second, revaluations can be expected to produce real effects since they affect the relative price between competitively and non-competitively produced commodities and the terms of trade.     

The effectiveness of pre-release advertising for motion pictures: An empirical investigation using a simulated market

We use data on a movie’s stock price as it trades on the Hollywood Stock Exchange, a popular online market simulation, to study the impact of movie advertising. We find that advertising has a positive and statistically significant effect on expected revenues, but that the effect varies strongly across movies of different “quality”. The point estimate implies that the returns to advertising for the average movie are negative.     

An empirical investigation of herding in the U.S. stock market

This paper proposes a new empirical testing method for detecting herding in stock markets. The traditional regression approach is extended to a vector autoregressive framework, in which the predictive power of squared index returns for the cross-sectional dispersion of equity returns is tested using a Granger causality test. Macroeconomic news announcements and the aggregate number of firm-level news items are treated as conditioning variables, while the average sentiment of firm-level news is treated as jointly determined. The testing algorithm allows the change points in the causal relationships between the cross-sectional dispersion of returns and squared index returns to be determined endogenously rather than being chosen arbitrarily a priori. Evidence of herding is detected in the constituent stocks of the Dow Jones Industrial Average at the onset of the subprime mortgage crisis, during the European debt and the U.S. debt-ceiling crises and the Chinese stock market crash of 2015. These results contrast with those obtained from the traditional methods where little evidence of herding is found in the US stock market.     

An empirical investigation of organizational memetic variation

The potential of a theory based on organizational memes in coevolution with the environment has been postulated, but remains empirically under-developed. This study explores whether understanding organizational memetic variation is empirically possible and, if so, whether it might, with further development, provide managers with early indications of a misalignment between organizational action (operationalized as memetic variation) and strategic intent—the amount of memetic variation needed to stay aligned with the competitive environment. A method for empirically identifying knowledge-based memes in everyday practice is developed. It stems from modern advances in genetics allowing micro-level changes in genes to be linked to macro-environmental dynamics. Using the concept that memetic variation is caused by everyday, uncontrollable uncertainties of interpretation, memetic variation is reduced to seven categorical types. A highly exploratory quasi-experimental design allows a preliminary comparison of a would-be innovative ‘Portfolio Management Committee’ with self-organizing Internet chat-room settings that are representational of open-source innovation. Results are consistent with predictions showing that higher levels of variation are seen in the latter, despite the former’s strategic intent of innovating to stay aligned with a dynamic environment. Further work is needed, however, to test reliability and validity.      

An empirical investigation of long-run growth in the UK

In this paper the long-run growth of the UK economy is analysed over the period 1855–1997, using a Markov-switching cointegration approach. We find that long-run economic growth can be explained by two permanent shocks, namely a technological shock and a labour supply shock. While technological progress seems to have a positive impact on the wage share and on income equality, the labour supply shock has the opposite effect, contributing to income inequality. Both shocks have a positive impact on aggregate output, but the bulk of long-run output growth variability is explained by the labour supply shock, suggesting that inequality is not harmful to growth.     

The empirical study on price discovery of cornstarch futures market in China

This article aims at exploring the performance of the price discovery function of cornstarch futures market in China. In order to test the stationarity of the cash and futures prices of cornstarch, the augmented Dickey–Fuller test is applied. Both prices are integrated of order one. Then, the Johansen cointegration test is conducted to test the cointegrating relationship between those two prices. Finally, the Granger causality test is performed to observe the direction of causality. The evidence shows that there is a long-run relationship between cash and futures prices and the futures price Granger causes cash price. As a whole, price discovery of cornstarch market in China is present although it is a newly emerged market.     

An empirical investigation of monetary interaction in the Korean economy

This paper conducts an econometric investigation of monetary interaction in the Korean economy over the past two decades. The study pays close attention to a critical role played by broad money and an interest rate term spread in the economy. A vector autoregression reveals two cointegrating relationships, both of which are consistent with macroeconomic theory: the first relationship corresponds to a broad money demand function, while the second represents a monetary policy rule function. The cointegrated system is then reduced to a vector equilibrium correction system, which characterizes the interaction between money demand and monetary policy rule. It is also demonstrated that the preferred model is a reliable forecasting device, suggesting that the broad money contains information about the real economy in the future.     

An empirical research of crude oil price changes and stock market in China: evidence from the structural breaks and quantile regression

This article investigates the relationship between real crude oil price changes and the Chinese real stock market at the industry level. Our study uses monthly data over the period 1994:03 to 2013:12. Based on input–output (IO) tables, this article will explore more details for the driving factors of sensitivity to oil price changes. We divide these driving factors into cost- and demand-side dependence. Empirical results reveal that sensitivity varies across different industries and periods based on structural breaks and asymmetric effects of oil price changes. Furthermore, some industries seemingly not directly affected by oil are sensitive to the real oil price changes. Finally, using a penalized quantile regression for panel data, we find that these two factors significantly affect lower, but not upper, quantile of sensitivity.

An empirical examination of factors driving the offshore renminbi market

Following the 2010 establishment of the offshore renminbi market in Hong Kong, renminbi deposits there quickly rose above RMB 1 trillion. In this article, we examine fluctuations between the offshore value of the renminbi in Hong Kong and its onshore value in mainland China. The size of the spot market spread appears to be influenced by stock market sentiment as reflected in the spread between A-shares listed in Shanghai and H-shares listed in Hong Kong. There is also some evidence of a link between the spread and the pace of renminbi deposit growth in Hong Kong.     

Mergers in the food retailing sector: An empirical investigation

We address the problem of merger evaluation, for competition policy purposes, in the retailing sector. The likely effects of a possible merger are analysed ex ante. The novelty of the paper lies in the inclusion of downstream and upstream market power effects on the retailers. Also, it provides an empirical application to the Portuguese food retailing market. The effects of additional concentration on prices are estimated, as well as the price reduction insiders are likely to obtain via an improved bargaining position. The final effect on prices depends on how these cost reductions are reflected in insiders’ prices, i.e., on the pass-through rate. For realistic values of this rate we find that the merger in question will most likely increase consumer prices and, therefore, should not be allowed on an antitrust legislation basis.     

Competition and the price of municipal cable television services: An empirical study

This paper investigates the effect of competition in the provision of cable television services on social welfare. We develop a simple theoretical model that suggests that competition will be welfare enhancing so long as it results in lower market prices. We empirically test for the presence of this condition by estimating a five equation system: First, the local franchising authority is viewed as self-selecting into a competitive or non-competitive environment in order to maximize its rents. Given this selection, the remaining four equations specify basic service and pay service penetration rate and price equations. Following Mayo and Otsuka (1991), the resulting system is estimated by two-stage least squares. We find that competition among suppliers lowers average basic cable rates by about $3.85 and the typical pay service rate by about $1.10, certis paribus. Mutatis mutandis estimates of these effects imply that monopoly franchising of cable service results in roughly $3.6 billion per year national welfare loss.     

The role of small bettors in price formation in betting exchanges

ABSTRACT

The presence of small bettors in betting exchanges generates mispricing, which can lead to exploitation by informed traders or result in permanent price deviations. This paper shows that mispricing from this source is also dependent upon variables of established relevance such as tournament round, the level of attention to the event, the volume of the betting, and bet type, further confirming these findings by means of cumulative accuracy profile (CAP) curves. It also offers evidence of the relevant role played by the type of device used to place the bet, whereby higher mispricing is observed in live bets placed via a mobile device, which appears to be associated with impulsive betting. This last finding could have practical implications for the regulation of the use of mobile devices to access gambling platforms.     

The labour income share and the relative price of investment in the US: an empirical investigation

Several studies argue that the recent decline in the secular trend of the labour income share is mostly driven by capital-embodied technological progress which is typically identified with trend reductions in the relative price of investment. In this paper, I use data from the United States to assess the nature of the relationship between trends in the labour share and the relative price of investment. Results from co-integration tests reveal that the share and the relative price of investment are most likely not co-integrated. However, co-variation tests indicate that both time series share a common stochastic component, and additional tests of structural breaks point at the presence of a common change in the mean or trend of both series. These results suggest that capital-embodied or investment-specific technological progress may have played an important role in the decline of the secular trend of the labour share.     

An investigation into the interdependence of global water indices: a VAR analysis

We investigate the extent and manner of equity price interdependence among four water indices – World Water Index, S-Network Global Water index (S-Net), S&P Global Water Index (S&P) and MSCI ACWI Water Utilities Index (MSCI ACWI) using the vector autoregression (VAR) framework for the period 2004–2014. We also employ methods of Granger causalities, variance decomposition and impulse responses. We find Granger causality significance between S-Net and MSCI ACWI and S-Net and S&P indices at the 1% level of significance, suggesting that the indices are significantly linked. Further, S-Net is the most influential index amongst them in the forecast variance that can be accounted by S-Net at level of 55.75%. Our study indicates that the four water indices are interdependent and related, so the water indices are influenced by movements in the other water indices.     

个人信用征信与保护的冲突与平衡

Regional wages and market potential in the enlarged EU: an empirical investigation

This article empirically analyses the link between market potential and regional wages in the enlarged EU. We contribute to the existing literature in several ways: (1) we analyse the link between market potential and wages for the EU27 and (2) deconstruct total market potential into several geographical components and analyse their respective contributions to explaining the geographical wage structure. We correct for existing spatial autocorrelation and endogeneity by using an instrumental variable generalized spatial two-stage least squares (IV GS2SLS).
