The effect of uncertainty on UK investment authorisation: Homogenous vs. heterogeneous estimators

This paper compares pooled and non-pooled models of UK capital investment using the Confederation of British Industrys (CBI) Industrial Trends Survey, focusing on the impact of uncertainty. The uncertainty measure is based on the cross sectional dispersion of optimism about the future business conditions in the industry in which the firm operates. The panel data estimation shows that uncertainty has quantitatively important negative effects on investment. However, if we look at the estimation results at the industry level, we find a great diversity in both estimated elasticities and t-statistics, providing valuable information not available from the pooled model. Finally, we compare the forecast performances of the above models; this analysis confirms that pooled estimators are generally better than non-pooled estimators in terms of out-of-sample forecast performance, but the difference between the two is not very large.     

An econometric analysis of the effects of market liberalization on price dynamics and price volatility

The paper investigates price dynamics under market liberalization, with a focus on the effects of lowering price floors. We analyze price dynamics by specifying and estimating a dynamic Tobit model under time-varying volatility, where the market price is censored by a government-set support price. The model is applied to the U.S. butter market over the last three decades. The econometric results show how the price support program affects both expected prices and the volatility of prices. It is found that the censoring effects of a price support program can be significant and large even if the price support is set relatively low.

Exploring the effect of crisis on cooperatives: a Bayesian performance analysis of French craftsmen cooperatives

ABSTRACT

The aim of this paper is to understand the economic performance of craftsmen cooperatives during the crisis period. These cooperatives have the distinctive feature of being supply cooperatives. We use an exhaustive dataset for the French craftsmen cooperatives (2004–2014). We estimate Bayesian Translog econometric models in order to underline the impact of the 2008 crisis on these cooperatives. On the one hand, cooperatives’ turnover and economies of scales decrease during the crisis, the effect is lower for elder cooperatives and varies across sectors. On the other hand, there is a convergence towards the mean for the various generations of cooperatives. These findings are robust to alternative econometric specifications.     

Cointegration relationships and hedonic pricing of differentiated commodities: an application to price dynamics in the US dairy sector

This study investigates the implications of hedonic pricing for price dynamics of differentiated commodities. A conceptual model of hedonic pricing is developed under a Leontief technology, showing how commodity prices reflect the underlying value of their components. Implications for the existence of cointegration relationships among commodity prices are derived. An application to the pricing and dynamics of selected US dairy commodities is presented. It provides evidence on the role of component valuation in the dynamics of dairy commodity prices in the short run as well as in the long run. Distinguishing between market regime and government regime (when the government price support is active), the analysis finds significant differences in dairy price dynamics between the two regimes.

The non-linear impact of oil price on the oil demand

ABSTRACT

A panel smooth transition regression model was adopted to analyse the non-linear impact of oil prices on oil demand. Data for 42 countries was obtained from the International Energy Agency for the time period spanning from January 1990 to June 2017. The results indicate that a threshold value does exist. Furthermore, when the oil price was lower than this threshold value, a positive relationship between oil price and oil demand was observed. When the price of oil was higher than the threshold value, however, a negative relationship between price and demand was found.     

Effects of exchange rate volatility on bilateral import performance of Vietnam: A dynamic Generalised method of Moments panel approach

The paper examines to what extent exchange rate volatility affects Vietnam’s bilateral import value. The two-step system generalized method of moments (GMM) was employed on panel data over a 10-year period. Exchange rate volatility was generated by two measures, including generalised autoregressive conditional heteroskedastic (GARCH) and moving standard deviation (MOVSD). A variety of diagnostic tests which ensure the consistency of GMM estimates were discussed. The main findings confirm that all explanatory variables demonstrated the expected signs, and exchange rate volatility has positive impacts on Vietnam's import flows. However, there is a large overall difference between the results produced with those two volatility measures.     

The impact of trade openness on technical efficiency in the agricultural sector of the European Union

The aim of this study is to analyse the impact of trade openness on technical efficiency of the European Union’s (EU) agricultural sector. There are no systematic theories linking trade policy to technical efficiency; hence, the relation between trade liberalization and technical efficiency is fundamentally ambiguous. Stochastic frontier analysis is used to model the relationship between EU’s production resources and agricultural output, as well as the importance of trade openness on technical efficiency of a country. The data for 16 of the 28 EU members were available for the period 1980–2007 including land, capital, fertilizer, labour, agricultural GDP, foreign direct investments (FDI), exports and import data. Results indicate that trade openness has an immediate, negative impact on efficiency in the EU agricultural sector. Over time, however, trade openness does increase efficiency. The FDI outflows increase efficiency. This suggests that an initial reduction in capital supply forces EU nations to utilize other factor inputs more efficiently. However, there is the unexamined potential that over time the depletion of capital results in a decrease in efficiency. Finally, formerly communist member-countries of the EU are found to have the lowest technical efficiency scores whereas Southern European nations have the highest efficiency.

The impact of institutional volatility on financial volatility in transition economies

What have been the determinants of financial volatility in the transition countries of Central and Eastern Europe and the former Soviet Union? This paper posits that institutional changes, and in particular the volatility of crucial institutions such as property rights, have been the major causes of financial volatility in transition. Building a unique monthly database of 20 transition economies from 1991 to 2017, this paper applies the GARCH family of models to examine financial volatility as a function of institutional volatility. The results show that more advanced institutions help to dampen financial sector volatility, while institutional volatility feeds through directly to financial sector volatility in transition. Democratic changes in particular engender much higher levels of volatility, while property rights are sensitive to the metric used for their measurement.     

The impact of exchange rate volatility on commodity trade between the US and Thailand

The impact of exchange rate volatility on trade flows continues to occupy the international finance literature. More recent studies have deviated from the traditional approach of using aggregate trade flows and have employed trade data at commodity level. This study investigates the impact of exchange rate uncertainty on the trade flows of 118 US exporting industries to Thailand and 41 US importing industries from Thailand. We find that exchange rate uncertainty has short-run effects on the trade flows of most industries. In the long-run, the main determinants of the trade flows are the level of economic activity in both countries.     

Economies of scale and scope in the European banking sector

In this article, using the data of 2008, we try to describe the impact of scale and product differentiation in 282 European banks. While evidence of the economies of scale is less clear, the results obtained using a translogarithmic function system show that significant economies of scope do exist even for new banking products like derivatives.

The Case for International Coordination of Electricity Regulation: Evidence from the Measurement of Efficiency in South America

A decade of experience has shown that monitoring the performance of public and private monopolies is the hardest part of electricity sector reform in South America—because operators control most of the information needed for effective regulation. South American electricity regulators can reduce this information asymmetry by increasing international coordination and relying on comparative measures of efficiency. To make it possible for them to do so, countries should harmonize their regulatory databases and develop methodologies for making comparisons. This paper uses data envelopment analysis and stochastic frontier analysis to estimate the efficiency of South America's main electricity distribution companies. Both approaches allow regulators to use relatively simple tests to check the robustness of their findings, strengthening their positions at regulatory hearings.     

The exchange paradigm of constitutional economics: implications for understanding the third sector

This paper reconsiders the exchange paradigm of constitutional economics from the perspective of the theory of the division of labor. According to this theory, human wants can be satisfied by two basic mechanisms—exchange and self-sufficiency. The exchange paradigm of constitutional economics emphasizes the former mechanism while neglecting the latter. Building on major economic theories of the third sector, it is argued that the latter mechanism is more helpful than the former in explaining the existence of third sector organizations. The paper concludes by discussing implications of this argument for the further development of constitutional economics.      

证券投资基金投资风格对心理账户的门限效应

针对国内证券投资基金的风格漂移现象,本文引入Hansen(1999)面板门限计量经济模型,对Fama—French三因子模型进行估计,以揭示基金投资风格漂移与投资者心理账户之间的非线性关系。发现基金投资决策并非依赖于自身的当前收益,而是依赖于持仓调整后市场平均收益,这是基金投资风格周期性漂移和趋同的主要原因。基金风格在市场收益为-0.073和0.182处发生普遍调整在高于0.182或低于-0.073时,基金都更偏好大盘股和高账面市值比股票。这一结果与前景理论中的心理账户效应相符,而并非完全是羊群效应导致。
