    Indirect benefits of infrastructure improvement in the case of an imperfect labor market
    Xueqin Zhu, Xueqin ; Ommeren, Jos van; Rietveld, P. - \ 2009
    Transportation Research. Part B, Methodological 43 (2009)1. - ISSN 0191-2615 - p. 57 - 72.
    unemployment benefits - equilibrium - agglomeration - models - wages
    We perform a welfare analysis of transport infrastructure improvements in the presence of an imperfect labor market, allowing for endogenous wages and involuntary unemployment. Efficiency wage setting is incorporated in a spatial two-region general equilibrium model, written as a welfare program. In our model, firms set wages above the market clearing level to create an inducement for employees not to shirk. The economy-wide effect (i.e. social welfare or total welfare) consists of the direct effect in transport market and the indirect effect in other markets. We conduct welfare analyses different from the conventional cost-benefit analysis, in which we distinguish between the direct welfare effect based on consumer surplus in the transport market and the indirect welfare effect through changes in regional unemployment, which is captured in the economy-wide effect. In our model, infrastructure improvement may increase unemployment in one region, but overall unemployment levels fall. The indirect welfare effects through decreases in overall unemployment are about 10-20% of the direct welfare effects for most plausible labor market parameters. The indirect welfare effects are larger, the poorer the initial transport infrastructure and the larger the labor market imperfections
    Food &Fun : De verwachtingen van bezoekers aan een multifunctioneel bedrijf
    PPO Akkerbouw, Groene Ruimte en Vollegrondsgroente, ; Ommeren, B. van - \ 2009

    consumenten - perceptie - consumentenonderzoeken - houding van boeren - multifunctionele landbouw - consumers - perception - consumer surveys - farmers' attitudes - multifunctional agriculture
    Overheden, instanties en onderzoekers tuimelen over elkaar heen om multifunctionele landbouw aan te prijzen als een van de economische peilers van het platteland. Maar omdat deze sector heel divers is, heeft men te maken met zeer verschillende bezoekers. (Groot-)ouders met kinderen, natuurvoedingsconsumenten, zorgvragers en vakantiegangers - iedereen zoekt het zijne op het multifunctionele bedrijf
    ENBB ; beoordeling Enkadrain op stortplaatsen i.r.t. levenduur van 100 jaar

    Afdichtingsmateriaal Enkadrain dient als bovenafdekking van stortplaatsen. De mat dient als alternatief voor de drainage die in het Stortbesluit is voorgeschreven. Het uitgangspunt voor een levensduur van 100 jaar is dat de hemelwaterafvoer gedurende die periode volgens de eisen van het Stortbesluit blijft functioneren. Het Expertisenetwerk Bodembescherming (ENBB) is een project van SenterNovem / Bodem+ en IPO
    Transport-related fringe benefits: implications for moving and the journey to work
    Ommeren, Jos van; Vlist, A.J. van der; Nijkamp, Peter - \ 2006
    Journal of Regional Science 46 (2006)3. - ISSN 0022-4146 - p. 493 - 506.
    residential-mobility - labor-markets - job search
    Firms offer compensation not only through wages, but also offer transport-related fringe benefits such as transport benefits (company cars, travel, and parking benefits) and relocation benefits to job applicants. We argue that these benefits are not randomly offered to employees, but depend on the job applicants' commuting costs. The firms' choice between these benefits affects the workers' incentive to move their residence closer to the workplace. Using information on firms' recruitment behavior in the United Kingdom, this paper shows empirically that the applicants' journey-to-work time induces firms to offer these benefits to job applicants. The implications of transport-related fringe benefits for commuting and relocation are found to be rather distinct. Transport benefits make employees less sensitive to the costs of commuting, whereas relocation benefits induce employees to move closer to the workplace.
