This chapter details a study of commodity value chain compression for coffee, cocoa, and sugar. The study uses time series data of prices along entire commodity chains from raw material in a commodity exporting developing country to final retail produce in a developed consuming country, in order to provide descriptive analysis of the evolution of farm gate-to-retail price spreads. Comparisons are made across the commodities studied and across countries in order to provide insight into the causes of changes in the farm gate-to-retail price spread over time.Less

This chapter shows that, while happiness is not the same with income, income still affects happiness. Indeed, the effect of income on happiness is one of the best-measured effects in all happiness research. It presents the evidence to this effect. Again, the chapter begins with evidence from the British Cohort Study, mostly cross-sectional. It then goes on to time-series data on individuals drawn from three panel studies for Britain, Germany, and Australia, as well as cross-section data on the United States. The chapter also examines the key role of social comparisons and adaptation, before tracing how the income factor is determined by earlier childhood experiences.Less

This book is concerned with recent developments in time series and panel data techniques for the analysis of macroeconomic and financial data. It provides an account of the time series techniques dealing with univariate and multivariate time series models, as well as panel data models. It attempts at an integration of time series, multivariate analysis, and panel data models. It builds on previous research in the areas of time series and panel data analysis, particularly recent developments in the analysis of panels with a large time series dimension and covers a wide variety of topics. The book begins with an overview of basic econometric and statistical techniques, and provides an account of stochastic processes, univariate and multivariate time series, tests for unit roots, cointegration, impulse response analysis, autoregressive conditional heteroskedasticity models, simultaneous equation models, vector autoregressions, causality, forecasting, multivariate volatility models, panel data models, aggregation and global vector autoregressive models (GVAR). The techniques are illustrated using Microfit 5 with applications to economic variables like real output and inflation and financial variables like, interest rates, exchange rates, and stock prices.Less

This chapter extends some of the models and procedures discussed in Chapters 2 and 3 to handle unbalanced panel data with unobserved heterogeneity. Types of unbalance are discussed and may affect the preferred procedure. Attention is given to the required modifications of the within-, between-, GLS- and OLS-estimators and their relationships. Two kinds of between-estimators are involved. Procedures for estimation of the variance components and joint ML estimation of coefficients and variance components are discussed.Less

This chapter looks at the impact of support price policy on the income from paddy crop. Markets for agricultural produces in India are mostly unorganized and distorted where farmers are often scrupulously exploited. Also since the elasticity of demand for agricultural commodities particularly foodgrains is less than unit, increased production during bumper harvest brings down the prices of agricultural commodities sharply. But, the support price provided to paddy has come under severe scrutiny for various reasons in recent years. Farmers have been demanding for higher support price for paddy but some economists argue that increase in paddy price is ‘dirty economics and dirtier politics’. With the help of time series data, chapter 4 provides an elegant analysis whether the support price scheme has helped paddy cultivating farmers in terms of increasing their income.Less
