Horticulture,livelihoods, and urban transition in Africa: evidence from South‐West Cameroon

This article documents change in periurban horticulture using repeat surveys in 1995 and 2004 of about 300 households around Muea, Cameroon. Real household incomes increased by 14%, with a large shift from farm to nonfarm income. Within agriculture, activity shifted from staple crops to horticulture, both for sale and in home consumption. In 1995, there were large remittances from farmers involved in periurban horticulture to their village of origin; in 2004 remittances continued and horticultural farmers were also heavily involved in informal financial associations. Periurban horticulture is disproportionately practiced by women and older workers, and plays an important and growing role in African livelihoods.     

Financial Market Turmoil： Implications for Monetary Policy Transmission in China

The recent financial market turmoil has initiated another search for insightful understanding of the interactions between the financial market and monetary policy. This paper explores these interactions in terms of the transmission mechanism of monetary policy in China. We argue that evolving financial development, enhanced by the expansion of the financial market, has altered the conventional channel for monetary transmission in China. Analyzing marked changes in the financial landscape and taking into account policy regime shifts in China, the paper provides clear evidence showing that the financial market has become a new and important channel for transmission of monetary policy in China.     

Driving on liquid sunshine – the Brazilian biofuel experience: a policy driven analysis

This paper analyses Brazil's experience with biofuels, focusing on the central role of the federal government as the main force driving the implementation of alternative locally produced ethanol (ethyl alcohol) and biodiesel. The pioneering, large scale ethanol programme that started over 30 years ago can be considered the most successful experience with the use of biofuels to date, as the government was able to rapidly implement the use of ethanol (ethyl alcohol) as a substitute for petrol in the 1970s and 1980s. The work contributes to the general discussion of sustainable and renewable energy sources and sets out the key policy mechanisms used. The paper also innovatively looks at the second large governmental intervention in the renewable fuels market – the biodiesel programme. In addition to the contribution to the debate surrounding command‐and‐control measures and economic incentive instruments, the paper analyses how lessons learned from the ethanol experiment were taken into consideration in the design and implementation of the biodiesel mandate, including social and environmental facets. It emphasizes the uniqueness of producing sugarcane ethanol in the Brazilian context and how attempts to carry out similar fast growing biofuels programmes may not be possible in other parts of the world.

Charter value,risk-taking and systemic risk in banking before and after the global financial crisis of 2007-2008

ABSTRACT

We investigate how bank charter value affects risk for a sample of OECD banks by using standalone and systemic risk measures before, during, and after the global financial crisis of 2007–2008. Prior to the crisis, bank charter value is positively associated with risk-taking and systemic risk for very large ‘too-big-too-fail’ banks and large U.S. and European banks but such a relationship is inverted during and after the crisis. A deeper investigation shows that such a behaviour before the crisis is mostly relevant for very large banks and large banks with high growth strategies. Banks’ business models also influence this relationship. We find that for banks following a focus strategy, higher charter value amplifies both standalone and systemic risk for large U.S. and European banks. Our findings have important policy implications and cast doubts on the relevance of the uniform more stringent capital requirements introduced by Basel III.     

CLOSED-FORM EXPRESSIONS FOR THE APPROXIMATE EVALUATION OF INTEREST RATES: EXTENSIONS TO THE GEOMETRIC SEQUENCE OF PAYMENTS CASE

For the case of a given sequence of constant payments, theoretical and numerical comparisons between two particularly simple closed-form expressions for the approximate evaluation of the interest rate are presented. It is also shown how these expressions can be generalized to cover the case where the sequence of payments follows a geometric progression.     

Friends or Foes? Mobile money interaction with formal and informal finance

Access to formal financial services is a key determinant of financial inclusion and yet, informal mechanisms still dominate the financial system in developing countries. In this context, the purpose of our article is to investigate how the growing effort to harness mobile money designed for unbanked individuals may help to overcome barriers to access formal financial services. Using a unique dataset obtained from an individual-level survey conducted in Burkina Faso, we explore the interplay between mobile money innovation and pre-existing formal and informal financial instruments. Our main findings show that, overall there are no differences in the inclination of mobile money users and non-users to make deposits in formal or informal deposit instruments. However, a closer investigation reveals suggestive evidence that it may increase the probability of participants in informal mechanisms to make deposits in formal financial instruments, especially using a bank account. Moreover, considering disadvantaged groups, we find for women, irregular income and less educated individuals that mobile money may increase their probability to make deposits in a bank and/or credit union accounts. Our results are robust to using instrumental variables and propensity score matching techniques that mitigate the endogeneity problem. They also pass a number of robustness checks as well as considering an alternative dataset. Given the low access to formal financial services in developing countries, our findings taken together indicate how the increasing adoption of mobile money may act as a stepping-stone towards financial inclusion.

Monetary,Financial and Fiscal Stability in the East African Community: Ready for a Monetary Union?

We examine prospects for a monetary union in the East African Community (EAC) by developing a stylised model of policymakers' decision problem that allows for uncertain benefits derived from monetary, financial and fiscal stability and then calibrating the model for the EAC for the period 2003–10. When policymakers properly allow for uncertainty, none of the countries wants to pursue a monetary union based on either monetary or financial stability grounds, and only Rwanda might favour it on fiscal stability grounds; we argue that robust institutional arrangements assuring substantial improvements in monetary, financial and fiscal stability are needed to compensate.     

Modeling US inflation dynamics: persistence and monetary policy regimes

This paper employs the recently developed structural stability test with multiple regime shifts and grid bootstrapping methods to model US inflation dynamics over the past half century. Our empirical results suggest that the persistence of inflation has witnessed significant declines over the most recent period of low inflation and this helps to embed a low inflation environment. The finding is robust to a variety of measures of the inflation series and offers new insight on understanding the stationarity issue of the US inflation series.
