Insect and other pests cause major economic damage on fruit crops in the tropics. However, some insects are beneficial and have a role in pollinating flowers, thus enabling fruit set. This book reviews these injurious and beneficial organisims and how they might be controlled to enhance fruit production and quality.

Emerging countries are increasingly concerned with improving their competitiveness and productivity. This Element develops a robust econometric methodology, based on controlling for usual unobservable effects at the firm or plant level. By robust empirical results in total factor productivity (TFP), we mean estimating investment climate (IC) elasticities, or semi-elasticities, with equal signs and similar magnitudes for more than ten different competing TFP measures. The key to achieve similar empirical results for several TFP measures is to avoid having a problem omitted variables, achieved through imputation of large proportions of missing observations in relevant variables (i.e. the capital stock). Furthermore through the use of a new concept of aggregate TFP (tfpIC), that measures the associated IC effects on firm´s tfp, we are able to make meaningful cross-country firm´s level productivity comparisons, avoiding the usual problem of comparing 'apples with oranges' that would otherwise occur if we directly compare country's TFP measurements.
