Financial Liberalization and Stock Market Efficiency: Causality Analysis of Emerging Markets

This paper studies the long- and short-run relationship between financial liberalization and stock market efficiency. It expands the extant body of knowledge by investigating Granger causality relationship applying mean group, common correlated effect mean group and common correlated effect pooled estimator to balanced panel data for 27 emerging markets over the period 1996–2011. We find evidence of financial liberalization Granger causes stock market efficiency, which is consistent with liberalization leads to efficiency hypothesis. Subsequently, our work makes a fresh contribution to the literature by focusing on informational efficiency of stock markets rather than financial development. Furthermore, we find that a negative long-term relationship between financial liberalization and stock return autocorrelation coexists with a positive short-term relationship between the two. The findings that financial liberalization, which has a deteriorated effect on stock market efficiency in the short-run, but positive impact in the long-run, allow us to draw an analogy similar to the J-curve hypothesis.     

Analysing Dutch dairy farmer behaviour towards the provision of public goods: The added value of an economic simulation experiment

The objective of this paper is to examine the value of experiments for assessing the impact of the proposed Common Agricultural Policy of 2013 on farm income and farming strategies. We focus specifically on the impact of an alternative direct payment system based on a flat rate and green payments. We show the added value of an economic simulation experiment to existing economic micro- and sector modeling analysis when analyzing farmer behavior. It is shown that the suitability of and rewards for the provision of green services play a significant role in their uptake by farmers and the support for them. These results are useful in implementing a revised direct payments system in the Netherlands for the future.     

Forecasting inflation in the European Monetary Union: A disaggregated approach by countries and by sectors

Inflation in the European Monetary Union is measured by the Harmonized Indices of Consumer Prices (HICP) and it can be analysed by breaking down the aggregate index in two different ways. One refers to the breakdown into price indexes corresponding to big groups of markets throughout the European countries and another considers the HICP by countries. Both disaggregations are of interest because in each one, the component prices are not fully cointegrated, having more than one common factor in their trends. The paper shows that the breakdown by group of markets improves the European inflation forecasts and constitutes a framework in which general and specific indicators can be introduced for further improvements.     

CHARTERS,PARTNERSHIPS AND NATURAL RESOURCES: TWO CASES OF ENDOGENOUS REGULATION IN ITALY

This paper illustrates two examples of natural resources management drawn from Italian history: the rural charter system in the current province of Trento and the rural partnership system in Nonantola in the province of Modena. These institutions lasted for many centuries, and survived and evolved in the contemporary legal system. It is concluded that both the cases can be defined as ‘robust’ institutions for the successful management of common pool resources.     

ECONOMETRICS FOR GRUMBLERS: A NEW LOOK AT THE LITERATURE ON CROSS‐COUNTRY GROWTH EMPIRICS

Abstract Since the seminal contribution of N. Gregory Mankiw, David Romer and David N. Weil in 1992 the growth empirics literature has used increasingly sophisticated methods to select relevant growth determinants in estimating cross‐section growth regressions. The vast majority of empirical approaches, however, limit cross‐country heterogeneity in production technology to the specification of total factor productivity, the ‘measure of our ignorance’. In this survey, we present two general empirical frameworks for cross‐country growth and productivity analysis and demonstrate that they encompass the various approaches in the growth empirics literature of the past two decades. We then develop our central argument, that cross‐country heterogeneity in the impact of observables and unobservables on output as well as the time‐series properties of the data are important for reliable empirical analysis.     

Strategic entry and externalities in groundwater resources: Evidence from the lab

This study uses economics experiments to extend the literature on common-pool resources by focusing on entry investment behavior in a stylized, spatially explicit aquifer. The model consists of a two-stage game, where participants make an entry decision in the first stage and, if they choose to enter, decide how much resource to extract in the second stage. Results show that entry behavior and groundwater pumping decisions are significantly affected by the underlying spatial externalities of the resource. In instances where the impacts of groundwater use are spread across all resource users, we observe both a greater number of users choosing to use the resource and a higher intensity of use. The results support expectations from the model that groundwater management policies should focus on entry in addition to decisions related to the volume of pumping. The results also discern the interplay of entry with both hydrogeologic characteristics of the resource and the option to exit and reveal that the option to exit increases the intensity of extraction as well as initial entry rates.     

Combining management plans and payment schemes for targeted grassland conservation within the Habitats Directive in Saxony,Eastern Germany

As central policies for biodiversity conservation in agricultural landscapes in the European Union (EU), the Habitats Directive and Agri-environmental programmes (AEP) have largely failed to halt biodiversity loss. In response, the German federal state of Saxony combined the instrument of management plans with AEPs to support the implementation of the Habitat Directive. In this study, we investigate the determinants of a farmers’ decisions to adjust their farming practices. Our data set consists of a quantitative survey with 131 farmers conducted between 2004 and 2011, complemented by implementation data from 333 grassland-plots. Determinants of farmers’ decisions to conserve grassland were estimated using a multinomial logit model. Our results show that a combination of management plans and AEPs can increase farmers’ disposition to adopt nature conservation measures. As central determinants, structural and location factors as well as the complementary provisiion of specifically designed AEPs increase farmers’ willingness to adopt conservation practices for grassland management. It can be concluded that additional costs are a major barrier to farmers’ adoption, particularly to those farms directing their farm management towards the optimisation of productivity and profitability . The findings highlight the complementary potential of integrated policy packages to incentivise specific measures of nature conservation within the framework of the Habitats Directive.     

Construct a composite indicator based on integrating Common Weight Data Envelopment Analysis and principal component analysis models: An application for finding development degree of provinces in Iran

Balanced development of regions requires the fair distribution of facilities and services. Hence, it is necessary to find and estimate the development degree of regions for policy makers. This paper presents an integrated Common Weight Data Envelopment Analysis (CWDEA) – Principal Component Analysis (PCA) model to find out the development degree of provinces in Iran. First, 131 suitable indicators are selected and then, the indicators are classified in fourteen different classes. In classical DEA model, each Decision Making Unit (DMU) is free to set its weights to reach the efficient frontier. In this paper, to restrict flexibility in indicator weights, development degree of provinces in each class is calculated using CWDEA model. Since, the proposed CWDEA model is not capable of fully ranking of provinces with all indicators, hence, the development degrees generated by CWDEA model are considered as indicators of PCA and the final ranks are obtained using PCA model. The results of proposed CWDEA-PCA model show that Yazd, Semnan and Bushehr are top three provinces in Iran.     

Passive farming and land development: A real options approach

The EU's farmers are no longer required to produce commodities to receive direct payments as long as they keep their land in good condition. Some believe this is bad for development because it encourages passive farming. We evaluate, using a real options approach, the implications of decoupled payments for the desirability and optimal timing of agricultural land development when considering sunk investment costs and uncertain future returns. We find that decoupled payments accelerate development while passive farming increases, by adding managerial flexibility, the value associated with land. We then use the Nash bargaining solution to identify the rental share to be paid for leasing land. We show that a deal for the lease of land can always be reached, but that the facility to use passive farming as an outside option allows landowners to extract policy rents, thereby undermining the potential for the Basic Payment Scheme to support tenant farmers’ incomes.
