‘One Stone Is Enough to Drive Away a Hundred Birds’: Peasants,Land and Resistance in Contemporary Afghanistan

Five books on the war in Afghanistan and contemporary Pakhtun life are reviewed from the perspective of the insights they provide into peasant resistance to the Afghan government and the United States. It is argued that while these books are important in improving our understanding of peasant resistance to the US‐led invasion of Afghanistan, with the exception of the monograph by Ahmed they offer only a partial account of the dynamics of resistance, because they fail to adequately integrate the ontology of the Pakhtun into their accounts, and the material foundations of that ontology. The result is that important elements of peasant resistance in Afghanistan are obscured.     

Non-monetary dimensions of well-being in South Africa, 1993–2004: A post-apartheid dividend?

Existing studies on shifts in income welfare in South Africa since the demise of apartheid suggest that income inequality increased, while headcount poverty rates declined since 2000, after some evidence of an increase or no change in poverty in the 1995–2000 and 1996–2001 periods. This study provides an analysis of the shifts in non-income welfare that have occurred in South Africa between 1993 and 2004. We use factor analysis to construct an asset index as a measure of non-income-based welfare. Variables reflecting household access to a range of services and assets are used in the construction of the index. Significantly different results emerge when non-income welfare shifts are considered: we show statistically significant decreases in the headcount asset poverty rates between 1993 and 2004 across a range of covariates. Finally, asset inequality decreased significantly between 1993 and 2004 – in stark contrast to results based on consumption data.     

THE TRANSMISSION MECHANISM IN GOOD AND BAD TIMES

Does the transmission of economic policies and structural shocks vary with the state of the economy? We answer this question using a strategy based on quantile regressions, which account for endogenous regressors and state‐dependent parameters. An application to U.S. real activity and interest rate reveals pervasive asymmetries in the propagation mechanism across good and bad times. During periods when real activity is above its conditional average, the estimates of the degree of forward‐lookingness and interest rate semi‐elasticity are significantly larger (in absolute value) than the estimates associated with below‐average periods. Results are robust to alternative strategies to model state‐dependent parameters.     

Distinguishing between individual‐and household‐level poverty

Drawing on survey data from 1995, this article shows that the level of aggregation is an important component in the analysis of poverty. Utilising the Headcount Index and cumulative distribution functions, the article examines earnings among individuals and households. Specifically, it is shown that poverty measures at the individual level, compared with estimates at the household level, will transmit differential rankings of indigence. Both are important predictors of poverty and hence should be coupled when trying to understand low earnings in a society.     

TIME‐VARYING DYNAMICS OF THE REAL EXCHANGE RATE: AN EMPIRICAL ANALYSIS

We use a time‐varying structural vector autoregression to investigate evolving dynamics of the real exchange rate for the UK, euro area and Canada. We show that demand and nominal shocks have a substantially larger impact on the real exchange rate after the mid 1980s. Real exchange rate volatility, relative to fundamentals, also shows a marked increase after this point in time. However, there is some evidence suggesting a closer business cycle co‐movement of the real exchange rate and fundamentals. Simulations from an open‐economy DSGE model show that these results are consistent with a decline in exchange rate pass‐through. Copyright © 2012 John Wiley & Sons, Ltd.     

The Macroeconomic Management of Increased Aid: Policy Lessons from Recent Experience

The authors investigate the macroeconomic challenges created by a surge in aid inflows. They develop an analytical framework for examining possible policy responses to increased aid, in terms of absorption and spending of aid—where the central bank controls absorption, through monetary policy and the sale of foreign exchange, and where the fiscal authority controls spending. Different combinations of absorption and spending lead to different macroeconomic consequences. Evidence from five countries that recently experienced an aid surge (Ethiopia, Ghana, Tanzania, Mozambique, and Uganda) shows no support for aid-related real exchange rate appreciation in these countries, but it does indicate that the fear of Dutch disease played an important part in the policy reaction to aid surges. Fiscal and monetary authorities should coordinate their responses to an aid surge, because an uncoordinated response—typically when the fiscal authority wants to spend aid while the central bank wants to avoid exchange rate appreciation—can have serious negative macroeconomic consequences.     

How long must a firm be great to rule out chance? Benchmarking sustained superior performance without being fooled by randomness

Although sustained superior firm performance may arise from skillful management or other valuable, rare, and inimitable resources, it can also result from randomness. Studying U.S. companies from 1965–2008, we benchmark how long a firm must perform at a high level to be confident that it is something other than the outcome of a time‐homogeneous stationary Markov chain defined on the state space of percentiles. We find (a) the number of sustained superior performers in Compustat, measured by ROA and Tobin's q, exceeds the number of false positives we would expect to be generated by such a process; yet (b) the occurrence of false positives is often enough to fool many observers, so (c) the identification of sustained superior performers requires particularly stringent benchmarks to enable valid study.

Tests for structural change,aggregation, and homogeneity

Structural change can be considered by breaking up a sample into subsets and asking if these can be aggregated or pooled. Strategies for constructing tests for aggregation and structural change in this setting have not received sufficient attention in the literature. Our methodology for testing generalizes to multiple regimes a discussion of Pesaran et al. (1985) for the case of two regimes. This treatment permits a unified approach to a large number of testing problems discussed separately in the literature, as special cases or as parts of a test of homogeneity. We also provide a simple alternative to much more complex testing strategies currently being researched and developed in testing for structural change.     

Does exchange-rate uncertainty matter in the Malaysia–E.U. bilateral trade? An industry level investigation

Due to ambiguity in the past literature, researchers have examined exchange rate volatility effect on trade using disaggregated data in recent years. Previous research has focused more on aggregated data having aggregation bias which has led to unnecessarily over-generalized findings. This study investigates the impact of exchange rate volatility on the Malaysian bilateral trade flows with European Union using industry level data. Our empirical findings, based on auto-regressive distributed lag framework, suggest that many import and export industries experience exchange rate volatility influence in the short run, while a very small number of industries show this effect in the long run. Moreover, the adverse impact of financial crisis (2007–2008) is more prevalent on import industries compared to export industries.     

Costos empresariales y reglamentación del trabajo en Sudáfrica

Los indicadores de las normas laborales publicados en el estudio del Banco Mundial Doing Business 2007 son ambiguos sobre la naturaleza e intensidad de la reglamentación del trabajo en Sudáfrica. Estos indicadores, al centrarse exclusivamente en la legislación, dan una imagen parcial, por lo que los autores exploran tres posibles elementos para ampliarlos con miras a trazar un panorama más realista de la situación normativa del mundo del trabajo: la «microlegislación>>, las instituciones la-borales y la interpretación judicial. Abogan por que se tengan muy presentes estos elementos al valorar el ordenamiento laboral.
