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 firms tfp, we are able to make meaningful cross-country
firms level productivity comparisons, avoiding the usual problem of
comparing 'apples with oranges' that would otherwise occur if we
directly compare country's TFP measurements.
This book is an up-to-date and comprehensive reference covering
pest management in organic farming in major crops of the world.
General introductory chapters explore the management of crops to
prevent pest outbreaks, plant protection tools in organic farming,
and natural enemies and pest control. The remaining chapters are
crop-based and discuss geographic distribution, economic importance
and key pests. For each pest the fundamental aspects of its
bio-ecology and the various methods of control are presented.
Understanding of the scientific content is facilitated with
practical advice, tables and diagrams, helping users to apply the
theories and recommendations. Handbook of Pest Management in
Organic Farming: * Consists of rational approaches and advice. * Is
authored by a team of international specialists in pest control. *
Represents the only available comprehensive review of insect pest
management in organic systems. This is an essential resource for
researchers and extension workers in crop protection, integrated
pest management and biocontrol, and organic farming systems.
Invasive arthropods cause significant damage in agricultural crops
and natural environments across the globe. Potentially threatened
regions need to be prepared to prevent new pests from becoming
established. Therefore, information on pest identity, host range,
geographical distribution, biology, tools for detection and
identification are all essential to researchers and regulatory
personnel. This book focuses on the most recent invasive pests of
agricultural crops in temperate subtropical and tropical areas and
on potential invaders, discussing their spread, biology and
control.
