Regional wage differences in the Netherlands: Micro-evidence on agglomeration externalities

Based on micro-data on individual workers for the period 2000-2005, we show that wage differentials in the Netherlands are small but present. A large part of these differentials can be attributed to individual characteristics of workers. Remaining effects are partially explained by variations in employment density, with an elasticity of about 3.8 percent and by Marshall-Arrow-Romer externalities, where doubling the share of a (2-digit NACE) industry results in a 2.4 percent higher productivity. We find evidence for a negative effect of competition (associated with Porter externalities) and diversity (associated with Jacobs externalities)

Micro-evidence on the determinants of innovation in the Netherlands: The relative importance of absorptive capacity and agglomeration externalities

This paper employs firm-level data to analyze the relative importance of firm characteristics and agglomeration externalities in explaining variation in innovation rates across firms. More specifically, we combine micro-data and census data to estimate the probability that a firm will introduce a goods, service or process innovation. We consider internal firm-level characteristics as well as externalities, using information on the regional production structure to test for Marshall-Arrow-Romer, Porter and Jacobs effects. Our results show that most firm-specific variables are highly statistically significant, whereas agglomeration variables are only significant for a few specific sectors, and even then only for some types of innovation

Correcting for primary study misspecifications in meta-analysis

In non-experimental sciences the errors associated with model misspecifications in primarystudies carry over to meta-analysis. We use Monte Carlo simulations to analyse the effects ofthese misspecifications on results of a meta-analysis using a meta-estimator that calculates asimple average effect and a meta-estimator that includes dummy variables to control forprimary study misspecification. The results show that using the dummy variable model goes along way in mitigating the negative effects of error propagation on the bias and mean squarederror of the meta-estimator, and the size and the power of statistical tests. Although primarystudy misspecifications can usually be observed and controlled for in a meta-analysis, themore complex interactions between these observed characteristics are far more difficult tocontrol for in practice. Our results show that these interactions may, however, substantiallyaffect the outcomes of a meta-analysis. When meta-analysis is used to look for a ‘true’ effectrather than for analysing variation in outcomes, our results provide an argument for studyselection on model quality to avoid the impact of error propagation in meta-analysis

Деякі аспекти методики аналізу сучасної музики

The violated in this article problem of the analysis of the modern music, complicated through the permanent growth of action of music outside factors of the modern music creation and its text transformations and anomalies, complications of communicative nature, is extraordinarily important in a scientifically-methodical plan. All these factors are in dissoluble communication, and it is therefore needed permanent and intent attention from the side of tutor, which forms the pupil's ability to correctly select strategy, tactics and tools of the analytical work

Competition between a maize crop and a natural population of Echinochloa crus-galli (L.) P.B.

In a field experiment, competition between maize cv. LG 11 and a naturally established weed population dominated by E. crus-galli was studied. At the av. E. crus-galli density of 100 plants/msuperscript 2, the yield of maize was reduced to only 18% of that of the weed-free control. This yield reduction strongly varied with years and the observed variation was probably related to differences between crop and weed in date of emergence. Experimental results were compared with the results of a simulation model for competition for light and water in crop-weed associations. (Abstract retrieved from CAB Abstracts by CABI’s permission
