Inflation and output dynamics with firm-owned capital

We model firm-owned capital in a stochastic dynamic New-Keynesian generalequilibrium model à la Calvo. We find that this structure impliesequilibrium dynamics which are quantitatively di¤erent from the onesassociated with a benchmark case where households accumulate capital andrent it to firms. Our findings therefore stress the importance ofmodeling an investment decision at the firm level in addition to ameaningful price setting decision. Along the way we argue that the problemof modeling firm-owned capital with Calvo price-setting has not been solvedin a correct way in the previous literature.

Downsizing, job insecurity and firm reputation

This paper studies how firms make layoff decisions in the presence of adverse shocks. In this uncertain environment, workers' expectations about their job security affect their on-the-job performance. This productivity effect on job insecurity forces firms to strike a balance between laying off redundant workers and maintaining survivors' commitment when deciding on the amount and timing of downsizing. This framework offers an explanation of conservative employment practices (such as zero or reduced layoffs) based on firms having private information about their future profits. High retention rates and wages can signal that the firm has a bright future, boosting workers' confidence. Moreover, the model provides clear predictions about when waves of downsizing will occur as opposed to one-time massive cuts.

The growth and diffusion of knowlegde and the theory of the firm

We analyze the implications of a market imperfection related to the inability to establish intellectual property rights, that we label {\it unverifiable communication}. Employees are able to collude with external parties selling ``knowledge capital'' of the firm. The firm organizer engages in strategic interaction simultaneously with employees and competitors, as she introduces endogenous transaction costs in the market for information between those agents. Incentive schemes and communication costs are the key strategic variables used by the firm to induce frictions in collusive markets. Unverifiable communication introduces severe allocative distortions, both at internal product development and at intended sale of information (technology transfer). We derive implications of the model for observable decisions like characteristics of the employment relationship (full employment, incompatibility with other jobs), firms' preferences over cluster characteristics for location decisions, optimal size at entry, in--house development vs sale strategies for innovations and industry evolution.

Waste Reduction, Construction and Demolition Debris: Guide for Building, Construction and Environmental Professionals, Revised November 2008

This document is intended to lay the foundation for resource reduction strategies in new construction, renovation and demolition. If you have an innovative idea or information that you believe should be included in future updates of this manual please email Shelly Codner at scodner@region12cog.org or Jan Loyson at Jan.Loyson@Iowalifechanging.com. Throughout this manual, we use the term “waste reduction” to define waste management initiatives that will result in less waste going to the landfill. In accordance with the waste management hierarchy these practices include reducing (waste prevention), reusing (deconstruction and salvage), recycling and renewing (making old things new again) - in that order. This manual will explain what these practices are and how to incorporate them into your projects.

Construction Code, November 25, 2008

Construction codes establish minimum standards for structural integrity, life safety, accessibility and energy conservation in construction of buildings and facilities intended for human occupancy. These requirements affect all of the major systems of buildings and facilities.

Ecole et construction du sens

Peut-on continuer à invoquer la neutralité abstentionniste de l'État pour proscrire un enseignement sur la religion à l'école ? Cet argument qui a eu sa légitimité historique vaut-il encore aujourd'hui ? En d'autres termes, l'existence d'un tel enseignement ne pourrait-il pas s'avérer compatible avec un régime de séparation Églises-État ? Qu'en pensent les acteurs directement concernés ? Refusant de rejeter la religion du côté du privé, les enseignants en nombre croissant déplorent le peu de place accordé à la « spiritualité » en classe. Quant aux élèves, reflétant l'attitude incertaine de leurs parents quant aux valeurs à transmettre, ils expriment des besoins plus difficiles à déchiffrer. Mais derrière ce débat relatif à l'inscription d'une case religieuse dans les programmes scolaires, ne s'en cache-t-il pas un autre touchant directement aux objectifs du système éducatif et au rôle des enseignants ?

Iowa Construction Site Erosion Control Manual, 2006

The purpose of this Iowa manual is to serve as a guide, provide solutions, and offer suggestions on construction sites to comply with Iowa's current soil erosion and storm water runoff regulations. This need is particularly important when land undergoes a land use change. Information provided in this manual will be helpful to land owners, developers, consultants, contractors, planners, local government, as well as the general public. This manual is intended to provide techniques that will meet the mandates of current legislation. Innovations that will benefit the user and still provide effective control are encouraged.

Do Agglomeration Economies Reduce the Sensitivity of Firm Location to Tax Differentials?

Recent theoretical work in economic geography has shown that agglomeration forces can mitigate 'race-to-the-bottom' tax competition, by partly or fully offsetting firms' sensitivity to tax differentials. We test this proposition using data on firm births across Swiss municipalities. We find that corporate taxes deter firm births less in more spatially concentrated sectors. Firms in sectors with an agglomeration intensity in the top quintile are less than half as responsive to differences in corporate tax burdens as firms in sectors with an agglomeration intensity in the bottom quintile. Hence, agglomeration economies do appear to attenuate the impact of tax differentials on firms' location choices.

Construction of Pseudomonas strains with improved biocontrol activity

Selected strains of fluorescent pseudomonads suppress various plant diseases caused by soil-borne pathogenic fungi, by a blend of several mechanisms including aggressive root colonization, antibiosis, competition for nutrients, induction of resistance in the plant, and enzymatic attack of the pathogen. These traits are amenable to genetic analysis and, therefore, to modification by genetic engineering. Biocontrol activities of Pseudomonas spp. have been enhanced in two ways: (i) by overexpression of traits known to involved in diseaese suppression, and (ii) by introduction of additional beneficial traits into strains having basal biocontrol activities. Under experimental conditions in microcosms, a number of genetically modified Pseudomonas strains have given promising results. It remains to be seen whether such strains will be superior to the best naturally occurring strains, applied singly or in combination, under greenhouse and field conditions.
