The sectoral effects of Brexit on the British economy: early evidence from the reaction of the stock market

We investigate the impact of the outcome of the EU referendum (Brexit) on various sectors of the British economy over the period June–July 2016. Using the event study methodology, we assess the effects of Brexit, relative to what had been anticipated, as measured by abnormal returns (ARs). The results show that the banking and travel and leisure sectors were affected negatively, with a cumulative AR of ?15.37% for the banking sector. We observe that Brexit has a mixed effect on ARs with apparent sector-by-sector differences.     

The impact of natural disasters on household income,expenditure, poverty and inequality: evidence from Vietnam

Natural disasters are expected exacerbate poverty and inequality, but little evidence exists to support the impact at household level. This article examines the effect of natural disasters on household income, expenditure, poverty and inequality using the Vietnam Household Living Standard Survey in 2008. The effects of a natural disaster on household income and expenditure, corrected for fixed effects and potential endogeneity bias, are estimated at 6.9% and 7.1% declines in Vietnamese household per capita income and expenditure, respectively. Natural disasters demonstrably worsen expenditure poverty and inequality in Vietnam, and thus should be considered as a factor in designing poverty alleviation policies.     

The effects of the Paris climate agreement on stock markets: evidence from the German stock market

We investigate the effects of the 2016 Paris Climate Agreement on the German stock market by considering the impact of 20 announcements pertaining to the Agreement on 17 industries. The event study methodology is used for this purpose, together with several robustness tests, such as the nonparametric rank test and non-parametric conditional distribution approach. The change in systematic risk following the announcements is captured by using various risk models. In general, we find that the Paris Climate Agreement is achieving its objectives in the short run. Our results show that the announcements affected polluting industries in terms of risk and return. Furthermore, we observe two distinct diamond risk structures when (1) Conference of the Parties (COP) 21 took place, and (2) the Agreement came into force.     

High corruption income in Ming and Qing China

We develop an economic model that explains historical data on government corruption in Ming and Qing China. In our model, officials' extensive powers result in corrupt income matching land's share in output. We estimate corrupt income to be between 14 and 22 times official income resulting in about 22% of agricultural output accruing to 0.4% of the population. The results suggest that eliminating corruption through salary reform was possible in early Ming but impossible by mid-Qing rule. Land reform may also be ineffective because officials could extract the same rents regardless of ownership. High officials' incomes and the resulting inequality may have also created distortions and barriers to change that could have contributed to China's stagnation over the five centuries 1400–1900s.     

Risky arbitrage,asset prices,and externalities

We introduce a no-risky-arbitrage price condition (NRAP) for asset market models allowing both unbounded short sales and externalities such as trading volume. We then demonstrate that NRAP is sufficient for the existence of competitive equilibrium in the presence of externalities. Moreover, we show that if all risky arbitrages are utility increasing, then NRAP characterizes competitive equilibrium in the presence of externalities. We are indebted to an anonymous referee for helpful comments on an earlier version of this paper. Page and Wooders are especially grateful to CERMSEM and EUREQua for their support and hospitality which made possible our collaboration.     

Cost and environmental efficiency of rice farms in South Korea

We examine cost and nutrient use efficiency of farms and determine the cost to move farms to nutrient‐efficient operation using Data Envelopment Analysis (DEA) with a dataset of 96 rice farms in Gangwon province of South Korea from 2003 to 2007. Our findings show that improvements in technical efficiency would result in both lower production costs and better environmental performance. It is, however, not costless for farms to move from their current operation to the environmentally efficient operation. On average, this movement would increase production costs by 119% but benefit the water system through an approximately 69% reduction in eutrofying power (EP). The average estimated cost of each EP kg of aggregate nutrient reduction is approximately one thousand two hundred won. For technically efficient farms, there is a trade‐off between cost and environmental efficiency. We also find that the environmental performance of farms varies across farms and regions. We suggest that agri‐environmental policies should be (re)designed to improve both cost and environmental performance of rice farms.     

Does WTO accession matter for the dynamics of foreign direct investment and trade?

The aim of this article is to study the impacts of World Trade Organization accession on the dynamics of foreign direct investment (FDI) and trade in Vietnam. In order to do this, we employ an augmented gravity model and use a panel data set covering bilateral trade and FDI between Vietnam and its 17 most important partner countries, over the period 1990–2008. Firstly, we find that WTO accession has a significantly positive effect both on Vietnam’s imports and on inward FDI. Secondly, even though we find no evidence to demonstrate convincingly that WTO accession influences Vietnam’s exports, this accession seems to indirectly encourage Vietnam’s exports through the FDI channel due to a strong connection between these two.     

Growth, volatility and stabilisation policy in a DSGE model with nominal rigidities and learning-by-doing

The paper aims to analyse the question of how cyclical fluctuations might affect long run growth. The analysis is based on a dynamic stochastic general equilibrium model for an imperfectly competitive economy with fully optimising agents. The model is characterized with nominal rigidities, an endogenous technology, and multiple shocks. It predicts either a negative or positive relationship between short run volatility and long run growth depending on the source of shocks and the reaction of the central bank. The model also shows that, even when the negative relationship exits the policy that is designed to stabilise short run volatility may either increase or decrease growth depending on the source of shocks.     

The effects of environmental regulation on the stock market: the French experience

The impact of environmental regulation on the French stock market is investigated by using event study methodology and asset pricing models. The impact of environmental regulation on the stock prices of environmentally friendly businesses and polluters is assessed. Additionally, we estimate the change in systematic risk following the introduction of new regulations. According to the results, the French stock market is particularly sensitive to the environmental regulation embodied in the European Union Emissions Trading System and less so to the regulation on water, soil and air. The chemicals, oil and gas industries exhibit negative reactions, whereas other polluters (such as construction and materials, and industrial transportation) produce positive abnormal returns.
