Environmental amenities and optimal agricultural land use: The case of Israel

This paper evaluates the effectiveness of changing land allocation among crops as a mechanism for increasing net-social benefits, where production profits and amenity values are augmented. A positive mathematical programming model is calibrated and applied to 43 regions in the northern part of Israel, using a crop-discriminating amenity-value function. Changes in land allocation increase net-social benefits by 2.4% nationwide and by up to 15% on the regional level, where in some regions the net-social-benefits-increase/profit-loss ratio exceeds 20. Therefore, the results indicate that a policy encouraging amenity-enhancement of agricultural land use is warranted, provided that it is implemented on a regional scale, rather than as a comprehensive nationwide-enforced program.     

A bioeconomic view of the transition to agriculture: a comment

Abstract Arthur Robson (2010) presents an ingenious model to explain why the standard of living apparently fell during the Neolithic transition from hunter‐gathering to agriculture. His demonstration relies on a production function that has a strong property with regard to technical change. This note shows how Robson’s result can be obtained using a more familiar set of restrictions on technical change. Under these restrictions, an improvement in technology will cause parents to invest less per child and the standard of living will fall.     

Green not (only) for profit: An empirical examination of the effect of environmental-related standards on employees’ recruitment

Thanks to an original database on French firms we investigate the impact of environmental-related standards on employees’ recruitment. Using a bivariate probit model, we show that voluntary environmental-related standards (i.e., ISO 14001 standard, organic labeling, fair trade, etc.) improve the recruitment of professional and non-professional employees. This finding suggests that, beyond environmental considerations, human resources management can drive registration.     

A methodology for constructing a financial systemic stress index: An application to Greece

The paper develops a financial systemic stress index (FSSI) for Greece. We present a novel methodology for constructing and evaluating a systemic stress index which i) adopts the suggestion of Hollo et al. (2012) [“CISS — A ‘Composite Indicator of Systemic Stress’ in the Financial System” ECB working paper] to incorporate time-varying correlations between different market segments, but uses a multivariate GARCH approach which is able to capture abrupt changes in correlations, shown to be a prerequisite for correctly identifying financial crises, ii) utilizes both market and balance sheet data which is a novel feature for systemic stress indicators and iii) evaluates the FSSI utilizing the results of a survey, conducted among financial experts, in order to construct a benchmark chronology of financial crises for Greece, which in turn is used to investigate whether changes in the FSSI are good leading indicators for financial crises. The results show that the FSSI is able to provide a precise periodization of crises. Our findings suggest that accurate depiction of the systematic nature of stress is pivotal in order to provide proper policy guidance with respect to financial crisis identification.     

The market for bushmeat: Colobus Satanas on Bioko Island

Species conservation is an important issue worldwide. The market for monkeys consumed as food on Bioko Island, Equatorial Guinea, is modeled as a bargaining game. The bargaining set-up leads to the conclusion that black colobus are being over-hunted. Using daily data an empirical density is fit to the price-quantity pairs resulting from exchange between buyers and retailers. The density provides support for the bargaining model. Quantile regressions are also fit to the data. The median quantile indicates buyers have greater bargaining power than retailers. Knowing who has bargaining power aids in the design of policy to reduce bushmeat hunting. Strategic elasticities are constructed from the quantiles. Given the harvest rate of monkeys and the elasticity estimates, the monkeys of Bioko Island are under considerable pressure.     

Did colonization matter for growth?: An empirical exploration into the historical causes of Africa's underdevelopment

We investigate the impact of 20th-century European colonization on growth. We find that colonial heritage, as measured by the identity of the metropolitan ruler and by the degree of economic penetration, matters for the heterogeneity of growth performances in Africa. Colonial indicators are correlated with economic and sociopolitical variables that are commonly employed to explain growth and there are growth gains from decolonization. Colonial indicators also add significant explanatory power to worldwide growth regressions and are correlated with the Sub-Saharan Africa and the Latin America dummies.     

The BMW Model: A New Framework for Teaching Monetary Economics

Abstract: Although the IS/LM-AS/AD model is still the central tool of macroeconomic teaching in most macroeconomic textbooks, it has been criticized by several economists. Colander (1995) demonstrated that the framework is logically inconsistent, Romer (2000) showed that it is unable to deal with a monetary policy that uses the interest rate as its operating target, and Walsh criticized that it is not well suited for an analysis of inflation targeting. The authors present a framework that develops the Romer approach into a very simple but, at the same time, comprehensive macroeconomic model. In spite of its simplicity, it can carry the main insights of the New Keynesian macroeconomics to an intermediate level and deal with issues like inflation targeting, monetary policy rules, and central bank credibility.     

The cost of natural capital consumption: Accounting for a sustainable world economy

The System for integrated Environmental and Economic Accounting (SEEA) has been criticized in this journal for ignoring the benefits of ecosystem services for human well-being. This paper argues that extended national accounts should not attempt measuring economic welfare. Rather, they could and should assess the environmental sustainability of economic activity as the cost of natural capital consumption. The global application of SEEA concepts and methods demonstrates the feasibility of international green accounting. For the world economy, sustainability costs run to about 3 trillion US$ or 6% of world GDP. Large variations at national and regional levels suggest that conventional economic indicators may significantly overstate economic progress in some parts of the world. Data gaps and lack of data comparability affect these first estimates. National and international statistical services should be more aggressive in greening the national accounts. More prudent and more sustainable economic policies might be the result.     

The relationship banking paradox: No pain no gain versus raison d'être

Relationship banking paradox refers to the case that credit market competition may threaten relationship banking practice, but it may stimulate it as well because of differentiation. Using a mixed model of adverse selection and double moral hazard, this paper shows that for some parameter values, relationship banking arises even when the banks compete à la Bertrand, hence supporting the no pain no gain hypothesis. This is due to multilayer nature of the information asymmetry by double moral hazard where an outside bank that does not have the borrower's proprietary information is unable to exert optimal levels of effort in the continuation game.     

The importance of the design of market-based instruments for CO2 mitigation: An AGE analysis for Spain

In the past few decades, economists have defended the use of market-based instruments (MBI) in environmental and climate policy. There have been many papers which have compared the costs of attaining environmental objectives with MBIs and with command and control instruments. However very few have compared different MBIs in examining these costs. This paper seeks to analyse various MBIs for CO₂ mitigation from the viewpoint of cost-effectiveness, using an AGE (applied general equilibrium) model for the case of Spain. A distinction is drawn between (1) quantity instruments, which represent different extents of a market for emission permits; and (2) price instruments, which represent different types of tax. Each instrument can affect different segments of the emission sources and therefore can have very different effects on the economy as a whole. We show how MBI can help to minimise mitigation costs, but also how taxes and tradable emission permits that are limited or constrained by many exemptions and distortions can raise costs considerably.     

Bayesian estimation of the output gap for a small open economy: The case of Canada

We introduce a novel approach for estimating output gaps for small open economies. Identification is based on a multivariate trend-cycle decomposition in which transitory exchange rate movements are linked to the output gap and inflation. The model is then applied to Canadian data.
