    Exits from unemployment : recall or new job

    This paper studies transitions out of unemployment in Spain distinguishing between recall to the same employer and reemployment in a new job. We use a large sample of newly unemployed workers obtained from Social Security records for Spain. These data contain information about each individual's employer identy before and after the unemployment spell. A discrete-time duration model with competing risks of exits serves us to investigate the factors that influence the probabilities of leaving unemployment to return to the same employer or to find a new job with a different employer. We find that the route to exit unemployment is determinant to understand the influence of individual an job characteristics on the hazard rate, as well as the latter dependence on unemployment duration. The recall hazard rate exhibits positive duration dependence during the first months and negative duration dependence thereafter (it is larger for females), while the new-job hazard presents positive duration dependence (it is larger for males

    Temperature dependence of breakdown and avalanche multiplication in In0.53Ga0.47As diodes and heterojunction bipolar transistors

    The avalanche multiplication and impact ionization coefficients in In/sub 0.53/Ga/sub 0.47/As p-i-n and n-i-p diodes over a range of temperature from 20-400 K were measured and shown to have negative temperature dependence. This is contrary to the positive temperature dependence of the breakdown voltage measured on InP/In/sub 0.53/Ga/sub 0.47/As heterojunction bipolar transistors (HBTs) in this and previous works. It is shown that the collector-base dark current and current gain can be the overriding influence on the temperature dependence of breakdown in InP/In/sub 0.53/Ga/sub 0.47/As HBTs and could explain previous anomalous interpretations from the latter

    Density dependence and the control of helminth parasites.

    No full text
    1. The transient dynamics and stability of a population are determined by the interplay between species density, its spatial distribution and the positive and negative density-dependent processes regulating population growth. 2. Using the human-helminth parasite system as an example, we propose that the life-stage upon which negative density dependence operates will influence the rate of host reinfection following anthelmintic chemotherapy, and the likely success of control programmes. 3. Simple deterministic models are developed which highlight how a parasite species whose population size is down-regulated by density-dependent establishment will reinfect a host population at a faster rate than a species with density-dependent parasite fecundity. 4. Different forms of density dependence can produce the same equilibrium behaviour but different transient dynamics. Under-representing the nature and magnitude of density-dependent mechanisms, and in particular those operating upon establishing life-stages, may cause the resilience of the parasite population to a control perturbation to be underestimated

    Unemployment duration and workers' wage aspirations in Spain

    Get PDF
    This paper examines unemployed workers' declared willingness to work for a wage lower than the one warranted by their qualification. We analyze which personal and economic characteristics determine this willingness and how it changes as unemployment spells lengthen. Moreover, we also study the influence of this willingness on unemployment duration. The main results are: (i) Young workers, those less educated and those living in regions with high unemployment show a more positive attitude towards accepting lower wages while married women with a working husband show more negative attitudes; (ii) The exhaustion of unemployment benefits has positive effects in the transition probability of the attitude from negative to positive; (iii) The effect of this attitude on the unemployment hazard rate is positive but only marginally significant which may be showing that this willingness is not only reflecting the worker's reservation wage but also some unobserved heterogeneity; (iv) The negative duration dependence of the unemployment hazard rate is substantially reduced when unobserved heterogeneity is controlled for.Willingness to work for lower wages, reservation wage, unemployment duration, unobserved heterogeneity

    The Influence of Dependence Structure And Relational Value on The Adoption Internet-enabled Supply Chain Management Systems

    Get PDF
    Based on resource dependency theory, this study investigates how the two dimensions of dependence – dependence asymmetry and mutual dependence – affect the adoption of internet-enabled supply chain management systems (eSCM). Drawing from the relational view of the firm, we argue that there are two types of relational value that can be provided by eSCM: relationship extendedness and relational depth. Dependence structure will influence firms’ incentive to obtain relationship extendedness and relational depth, which will in turn affect eSCM adoption. We collected data from mainland China using an online questionnaire and 212 valid samples were received. The emergent results show positive influence of dependence structure on relationship extendedness and relational depth. Positive effects of dependence structure and relationship relational depth on eSCM adoption are also found. However, the finding suggests a significant negative effect of relationship extendedness on eSCM, which is contradictory to the hypothesis. Future research is needed to interpret the counterintuitive finding

    Determinasi Karakteristik Pemerintah Daerah Terhadap Opini BPK

    The research objectives were to determine: 1). Effect of government size on BPK opinion 2). The influence of the level of regional dependence on the center on the BPK opinion, 3) The influence of level of prosperity on the BPK opinion, 4) The influence of the level of regional independence on the BPK opinion. The population in this study were districts and cities in Central Java for 2017 to 2019. The samples in this study used purposive sampling and logistic regression analysis methods. The test instrument used in this study used SPSS version 24. Partially, the size of government size has a negative and significant effect on BPK's opinion. The variables of the level of regional dependence on the central government and the level of prosperity have a positive and significant effect on BPK's audit opinion. Meanwhile, the level of regional dependence has a negative and insignificant effect on BPK's opinio
