  • death by market power reform competition and patient outcomes in the national health service
    American Economic Journal: Economic Policy, 2013
    Co-Authors: Martin Gaynor, Rodrigo Morenoserra, Carol Propper
    Abstract:

    The effect of competition on the quality of health care remains a Contested Issue. Most empirical estimates rely on inference from non-experimental data. In contrast, this paper exploits a procompetitive policy reform to provide estimates of the impact of competition on hospital outcomes. The English government introduced a policy in 2006 to promote competition between hospitals. Using this policy to implement a difference-in-differences research design, we estimate the impact of the introduction of competition on not only clinical outcomes but also productivity and expenditure. We find that the effect of competition is to save lives without raising costs.

  • death by market power reform competition and patient outcomes in the national health service

    Abstract:

    The effect of competition on the quality of health care remains a Contested Issue. Most empirical estimates rely on inference from non experimental data. In contrast, this paper exploits a pro-competitive policy reform to provide estimates of the impact of competition on hospital outcomes. The English government introduced a policy in 2006 to promote competition between hospitals. Patients were given choice of location for hospital care and provided information on the quality and timeliness of care. Prices, previously negotiated between buyer and seller, were set centrally under a DRG type system. Using this policy to implement a difference-in-differences research design we estimate the impact of the introduction of competition on not only clinical outcomes but also productivity and expenditure. Our data set is large, containing information on approximately 68,000 discharges per year per hospital from 160 hospitals. We find that the effect of competition is to save lives without raising costs. Patients discharged from hospitals located in markets where competition was more feasible were less likely to die, had shorter length of stay and were treated at the same cost.

  • food security and trade reconciling discourses in the food and agriculture organization and the world trade organization
    Food Security, 2015
    Co-Authors: Arild Aurvag Farsund, Carsten Daugbjerg, Oluf Langhelle
    Abstract:

    A Contested Issue in the international debate on food security is the role of trade in safeguarding food security at the global and national level. This paper explores how the Issue of food security and trade has been discursively framed in two international organizations, the Food and Agriculture Organization (FAO) and the General Agreement on Trade and Tariffs World Trade Organization (GATT/WTO), from 1945 to 2014. We argue that there are identifiable shifts in FAO’s positions on food security and trade in the 1980s and 1990s towards trade liberalization as advocated by the WTO. The official view of the WTO secretariat and many of its member states (proponents of trade liberalization in agriculture) is that trade liberalization is both necessary and conducive for food security. The FAO has adopted this discourse. Although this is the dominant discursive framing, counter-framings of the food security - trade problem has played an important role in the deadlock of the Doha Round negotiations. We consider how this may influence the global food trading regime.

  • On angular measures in axiomatic Euclidean planar geometry
    2021
    Co-Authors: Grötschel Martin, Hanche-olsen Harald, Holden Helge, Krystek, Michael P.
    Abstract:

    We address the Issue of angle measurements which is a Contested Issue for the International System of Units (SI). We provide a mathematically rigorous and axiomatic presentation of angle measurements that leads to the traditional way of measuring a plane angle subtended by a circular arc as the length of the arc divided by the radius of the arc, a scalar quantity. This abstract approach has the advantage that it is independent of the assumptions of Cartesian plane geometry. We distinguish between the geometric angle, defined in terms of congruence classes of angles, and the (numerical) angular measure that can be assigned to each congruence class in such a way that, e.g., the right angle has the numerical value {\pi}/2 . We argue that angles are intrinsically different from lengths, as there are angles of special significance (such as the right angle, or the straight angle), while there is no distinguished length in Euclidean geometry. This is further underlined by the observation that, while units such as the metre and kilogram have been refined over time due to advances in metrology, no such refinement of the radian is conceivable. It is a mathematically constructed unit, set in stone for eternity. We conclude that angle measurements are dimensionless, and the current definition in SI should remain unaltered

We provide a mathematically rigorous and axiomatic presentation of angular measure that leads to the traditional way of measuring a plane angle subtended by a circular arc as the length of the arc divided by the radius of the arc, a scalar quantity. We distinguish between the \emph{angular magnitude}, defined in terms of congruence classes of angles, and the (numerical) \emph{angular measure} that can be assigned to each congruence class in such a way that, e.g., the right angle has the numerical value $\frac\pi2$. We argue that angles are intrinsically different from lengths, as there are angles of special significance (such as the right angle, or the straight angle), while there is no distinguished length in Euclidean geometry. This is further underlined by the observation that, while units such as the metre and kilogram have been refined over time due to advances in metrology, no such refinement of the radian is conceivable. It is a mathematically defined unit, set in stone for eternity. We conclude that angular measures are numbers, and the current definition in SI should remain unaltered.Comment: The earlier version has been split into two companion parts.
