    This paper explores the role of incentives in the English NHS. Until financial year 2009/10, elective procedures that were cancelled after admission received a fixed reimbursement associated with a specific healthcare resource group code. We in- vestigate whether this induced trusts to admit and then cancel, rather than cancel before admission and/or to cancel low fee over high fee work. As the tariff was ended in April 2010 we conduct an interrupted time series analysis to examine if their behaviour was affected after the tariff removal. The results indicate a small, yet statistically significant, decline in the probability of a last minute cancellation in the post-tariff period, especially for certain types of patients and diagnoses.

    Background: In recent years, Greece has been in the spotlight as one of the countries hit the hardest by the European financial crisis. Yet evidence on the impact of the crisis on total and cause-specific mortality remains unclear. The paper explores whether the economic crisis has interrupted the level and/or the trend of mortality rates. Methods: We use regional panel data for the period 2001-2013 and adopt an interrupted time-series approach in order to test for any changes in a series of gender, age and cause-specific mortality trends. Findings: Our results show that overall mortality has continued to decline during the years of the financial crisis but at a slower pace (-0∙13 vs. -0∙065) and the trend difference is statistically significant (0∙062, p<0∙001). The trend difference is more evident for women (0∙087, p<0∙001) than for men (0∙040, p<0∙01). Older age groups have experienced more negative effects than the younger population, who have even seen some improvements in mortality trends. Deaths by diseases of the circulatory system have declined more slowly, while deaths from vehicular accidents have declined faster during the crisis, most prominently among young men. On the other hand, deaths from suicides, diseases of the nervous system and mental disorders have followed a positive upward trend during the crisis. We also find evidence that deaths due to medical errors during treatment have increased considerably during the crisis, affecting mainly older adults. Comparing the expected values of the during-crisis versus extrapolated before-crisis fitted, one estimates an extra 241 deaths per month during the crisis period with the largest contributor being an excess of 153 deaths per month from circulatory causes. Interpretation: The findings suggest that mortality trends have been interrupted during the years of the crisis, but that the changes vary by age, gender and cause of death. The increase of deaths due to medical errors may reflect the effects of quality deterioration during economic recessions.

    This study investigates nominal contractual base-wage adjustments in Greece associated with the 2011 industrial relations reform which re-defined the limits within which base wages could oscillate and allowed workers’ associations to negotiate for wages at the firm level. The assessment covers the period 2010–2013 and is based on information extracted from the universe of firm-level contracts signed in this period. We found that firm-level contracts increased dramatically shortly after the reform, now covering a larger pool of workers, especially in larger firms, and are associated with higher base-wage reductions in the post-reform period. At the firm level, wage reductions are higher when workers are represented by a workers’ association rather than a typical trade union. In addition, a heterogeneous effect is uncovered regarding the factors that shape base-wage adjustments (firm size, profitability, structure of bargaining body and aggregate unemployment) between new and traditional forms of workers’ representation in collective bargaining.

    This paper explores the relationship between unemployment and crime in Greece before and during the crisis using panel data at the regional level. The results indicate the operation of a positive relationship between specific crime categories and male unemployment only during the crisis, a weaker effect of long term unemployment only on the total criminal activity and they reveal the existence of significant dynamics.

    Using cross-sectional data from the Labour Force Survey, we investigate whether a wage curve, i.e. a negative relationship between real wages and regional unemployment, could be estimated in the Greek labour market and in the period 1999-2014. Adopting individual static and regional dynamic specifications, our results do not support the existence of such a relationship despite the extensive macroeconomic adjustment of real wages after 2009. However, allowing for period-specific heterogeneous slopes, we find that a negative relationship between wages and regional unemployment emerged in the period 2010Q2–2011Q4 which however was short-lived. This relationship appears to be exclusively due to the restructuring of the collective bargaining regime and the reduction in the national minimum wages, both of which were implemented in the private sector.

    This article analyzes the effect of firm-level contracting on the wage structure in the Greek private sector. Using a matched employer-employee dataset for 2006, unconditional quantile regressions and relevant decomposition methods, we identify a wage premium associated with firm-level contracting, which follows a hump-shaped profile across the wage distribution. Further, the wage differential between workers under firm-level and broader-level collective agreements can be primarily attributed to the differences in the regime-specific wage setting structure, for those below the median of the unconditional wage distribution, and to differences in worker and firm-specific characteristics for those in the upper tail. © 2012 Blackwell Publishing Ltd/London School of Economics.
