Examining the Link between Crime and Unemployment: A Time Series Analysis for Canada

We use national and regional Canadian data to analyse the relationship between economic activity (as reflected by the unemployment rate) and crime rates. Given potential aggregation bias, we disaggregate the crime data and look at the relationship between six different types of crimes rates and unemployment rate; we also disaggregate the data by region. We employ an error correction model in our analysis to test for short-run and long-run dynamics. We find no evidence of long-run relationship between crime and unemployment, when we look at both disaggregation by type of crime and disaggregation by region. Lack of evidence of a long-run relationship indicates we have no evidence of the motivation hypothesis. For selected types of property crimes, we find some evidence of a significant negative short-run relationship between crime and unemployment, lending support to the opportunity hypothesis. Inclusion of control variables in the panel analysis does not alter the findings, qualitatively or quantitatively

A dynamic small open economy model with involuntary unemployment

It is well known that real business cycle small open economy (SOE) models rely on Greenwood, Hercowitz, and Huffman (1988) preferences to match the countercyclical trade balance observed in open economies, as well as other second moments, while standard preferences à la King, Plosser, and Rebelo (1988) are commonly labelled `ineffective,' owing to their inability to yield the countercyclical trade balance. In this paper, I show that an SOE model with standard preferences and `involuntary' unemployment with efficient risk sharing can obtain a countercyclical trade balance and match main empirical regularities in small open economies.

Imperfect Competition, Nominal Wage Contracts and the Business Cycle

We introduce nominal wage contracts into a competitive and a noncompetitive labor market structure. We find these models to have similar business cycle properties, but we argue that the imperfectly competitive market structure is more appropriate for nominal wage contract analyzes. We introduce imperfect competition to the labor market by assuming that households have market power and consequently choose nominal wage contracts as part of their maximization problem, while in a competitive structure nominal wage contracts are introduced via an exogenous rule. The latter formulation lacks microeconomic foundation that makes the model inappropriate for the analysis of nominal wage contracts.

Reexamination of real business . . .

Standard dynamic small open economy models have predicted a counterfactual perfectly positive correlation between output and hours worked over the business cycle. In addition, this class of models exhibits a weak internal propagation mechanism. To address these anomalies, this paper incorporates intertemporally non-separable labor supply and variable capital utilization into the canonical Mendoza model with adjustment costs of net investment. Our analysis shows that a dynamic, technology-shock driven small open economy model with internal habit formation in labor hours and endogenous capital utilization is able to account for the main real business-cycle regularities of Canada after 1981

Gravimetric analysis of selecteD types of Biofuels

Biomass provides a great diversity of input materials and universal use, not only for heat generation but also electricity generation in modern incinerators. For the most eficient use of solid biofuels, it is necessary to know their physico-chemical properties. The work focuses on the gravimetric analysis of selected types of biofuels. This paper presents the results of measurements for moisture content, ash and combustibles in selected solid biofuels. Experiments represent a follow-up to measurements performed to date

Gas Emissions in Combustion of Biofuel

Nowadays, biomass or more precisely biofuel is more and more being exploited as a substitute for fossil fuels for heating as well as for example for heating a drying environment. This contribution focuses on assessing a heat source by combusting various types of solid biofuels. It is a boiler VIGAS 25 with AK 2000 regulation for heating a family house. Gaseous emissions were measured using a device TESTO 330-2LL. Firewood, peat briquettes, bark briquettes and hardwood briquettes were burnt. Results of experimental measurements concerning the production of gaseous emissions are processed in tables and graphs depending on boiler performance and combustion time
