The dominant practice in economics is to choose the mathematical specification of model relations on the basis of convenience, without much theoretical support. This paper discusses how quantitative model specifications can, in some cases, be given a more formal scientific underpinning in the...

Recently, there has been much discussion about replicability and credibility. By integrating the full research record, increasing statistical power, reducing bias and enhancing credibility, meta-analysis is widely regarded as 'best evidence'. Through Monte Carlo simulation, closely calibrated on...

Labor markets in low- and middle income countries are characterized by high levels of informality. A multitude of interventions have therefore been implemented in many countries with the objective to increase the formalization of firms and workers, including information campaigns, simplification...

Despite a growing interest in using satellite data to estimate paddy rice yield in Southeast Asia, significant cloud coverage has led to a scarcity of usable optical data for such analysis. In this paper, we study the feasibility of using two alternative sources of satellite data - (i) surface...

In the estimation of multiple output technologies in a primal approach, the main question is how to handle the multiple outputs. Often an output distance function is used, where the classical approach is to exploit its homogeneity property by selecting one output quantity as the dependent...

The authors point out that autocorrelation is an accidental statistical phenomenon. The cause of the occurrence of collinearity is the incomplete data base and that ideally, the elimination of the occurrence of autocorrelation is achieved by knowing the effect stage for all possible combinations...

Existence of a cointegration relationship between two time series in the time domain imposes restrictions on the series zero‐frequency behaviour in terms of their squared coherence, phase and gain, in the frequency domain. I derive these restrictions by studying cross‐spectral properties of...

Changes in time management reflect contemporary socio-economic trends. Indicators of the use of leisure time may be considered as unconventional measures of the quality of life. The structure of time budget, in addition to the structure of consumer spending, is also considered to be a...
