| FAO measure of undernourishment is calculated based on three main parameters: dietary energy supply (DES), minimum dietary energy requirement (MDER), and the coefficient of variation of dietary energy consumption (CV). In the current implementation of this methodology, the DES and the MDER change over time, as would be expected. The CV, however, remains constant. However, we expect the CV to change over time and be a function of income and prices. This paper discusses why the CV should change in response to changes in these variables, and suggests a practical way to estimate changes in the CV over time in the absence of survey data. |

| An important dimension of poverty is access to food. Household food security implies access to the food needed for a healthy and productive life. Lack of access to and/or impaired utilization of food contribute to household food insecurity. This study compares the usefulness of a standardized food insecurity scale for determining the food insecurity status of rural and urban households in Bangladesh and Uganda, and for predicting poverty status. The analysis uses data from the IRIS Composite Survey Household Questionnaire (2004), which consists of 1,587 households (approximately 800 households in each country). The coping mechanisms adopted in the presence of food shortages represent the building blocks for the development of the scale (7 items). In order... |

| Life cycle savings is proposed as one explanation for much of the increase in savings and economic growth in Asia. The association between the age composition of a nations population and its savings rate, observed within 16 Asian countries from 1952 to 1992, is reestimated here to be less than a quarter the size reported in a seminal study, which assumed lagged savings is exogenous. Specification tests as well as common sense imply, moreover, that lagged savings is likely to be endogenous, and when estimated accordingly there remains no significant dependence of savings on the age composition, measured in several ways. Research should consider lifetime savings as a substitute for children, and model the causes for the decline in fertility which changes... |

| An important feature of aid to developing countries is that it is given to the government. As a result aid has the potential to affect budgetary behaviour. Although the (albeit limited) aid-growth literature has addressed the effect of aid on policy, it has tended to neglect the effect of aid on the fiscal behaviour of governments. While fiscal response models have been developed to examine the effects of aid on fiscal aggregates - taxation, expenditure and borrowing - the underlying theory is ad hoc and empirical methods used are subject to severe limitations. This paper applies techniques developed in the "macroeconometrics" literature to estimate the dynamic structural relationship between aid and fiscal aggregates. Using vector autoregressive methods,... |

| We generalize the Tobit censored regression to permit unique unobserved censoring thresholds conditioned by covariates and a set of common response coefficients. This situation , we argue, is one arising frequently in applications of censored regression and we provide three diverse examples to motivate the theory. We derive a robust estimation algorithm with three noteworthy features. First, by augmenting the observed-data likelihood with the censored observations, the estimation strategy is the same as Chib (1992) who derives Bayes estimates of the conventional censored regression. Second, by virtue of its generality, the model is applicable to a much broader set of circumstances than the conventional Tobit regression, which is nested as a special case of... |

| There is little doubt that technology change, both in terms of its process and quality dimensions, represents the principal driving force to explain comparative economic performance at both micro and macro levels. This paper examines the sources of technology change and the impediments to the full realization of its opportunities, both abstractly and in the context of a comparison among six typologically diverse developing countries. Among the external sources, we examine the roles of trade, foreign patents and FDI; among the internal sources we examine the roles of investment, domestic R&D, domestic patents, S&T personnel and secondary education alternatives. Among impediments, we analyze certain public and private policy frameworks which tend... |

| This paper investigates the medium- and long-term growth effects of the global financial crises on Low-Income Countries (LICs). Using several methodological approaches, including impulse response function analysis, growth spells techniques and panel regressions, we show that external demand (ED) shocks are not historically associated with sharp declines in output growth. Given existing evidence that LICs were primarily impacted by such a shock in the global financial crisis, our analysis provides some optimism on the chances that LICs will avoid a protracted period of slow growth. However, we also show that there seem to be persistent output losses associated with ED shocks in the medium-run. In terms of policy implications, our analysis provides evidence... |

| A key objective of China's reform program was to reduce distortions in the economic system and enhance growth. However, when implemented in incremental and partial ways, local governments or individuals have chance to capture rents inherent in the reform process. Young (2000) warned that the rent-seeking behavior might lead to increasing market fragmentation. Empirical studies have since shown that this did not happen in the product markets. In this paper we argue that as rents from the product markets were squeezed out during the reform process, rent-seeking behavior shifted to the factor markets, especially the capital and land markets. The reform process now needs to be deepened to ensure that the factor markets also become more integrated and efficient. |

| Arthur Lewis seminal 1954 paper and its emphasis on dualism appeared at a time when neither the work of Keynes or Harrod-Domar nor the later neoclassical production function of Solow seemed relevant for developing countries. As a consequence, his model, rooted in the classical tradition, plus its many extensions, generated an extensive literature at the center of development theory. The approach also encountered increasingly strong criticism, some of the red herring variety, but some, spearheaded by neoclassical microeconomists like Rosenzweig, also raised serious challenges, focused especially on its labor market assumptions. This paper reviews this landscape and asks what theoretical or policy relevance the Lewis model retains for todays developing... |
