For a number of reasons, incomes vary strongly with age. The nature of this variation is of interest for a wide range of policy purposes. Since age structures differ across countries, knowledge about the incomes earned by different age groups is also necessary for understanding and interpreting international comparisons of overall inequality. This paper quantifies the economic well-being of different age groups and the extent to which they rely on incomes from public and private sources. The analysis aims at establishing how social benefits, and the taxes needed to finance them, affect income levels and income disparities across different age groups. Results are compared across nine OECD countries.

Port efficiency is an important indicator of port performance; more efficient ports lower transportation costs and facilitate imports and exports of a country. Despite the importance of the subject, the exisiting port efficiency studies have almost exclusively focused on container ports. This Working Paper aims to fill that gap by calculating efficiency scores of world ports per cargo type (containers, oil, coal, iron ore and grain). These calculcations have been made using a database constructed for this purpose. Several findings can be derived from these calculations. Significant improvements can be made when the technical efficiency of ports is increased. Among the sample, gaps between terminal efficiency mostly reflected gaps in pure technical efficiency. When comparing the level of efficiency achieved by ports across commodities, technical gaps were more marked for container and oil terminals. Promoting policies to raise throughput levels in order to minimise production scale inefficiencies is another important area for improvement. Production scale inefficiencies arise when throughput levels are below or above optimal levels given the current capacity of terminal infrastructure. Such inefficiencies were mostly found in a substantial number of ports handling crude oil and iron ore, suggesting that efficiency is more sensitive and driven by exogenous factors related to traffic flows. The analysis also shows that the size of ports matters for port efficiency. The crude oil, iron-ore and grain ports have higher efficiency scores at larger total port size, suggesting that this size is more efficient because they can drive technological development. Finally, there are regional patterns emerging across commodities. Terminals in China are among the most efficient in handling coal bulk and containers with terminals in Southeast Asia. By contrast, the most efficient grain and iron-ore terminals are located in Latin America, and the most efficient crude-oil transhipment terminals are mostly found in the Gulf region. Further, Australia is also found to perform well in handling coal bulk and grains.

Now that pollution is reaching worrisome levels in some countries and at the global level, there is a growing consensus that it needs to be explicitly considered as a by-product of the production process and incorporated in economic decisions. But this is not easy in the absence of markets and observable prices. Shadow prices of pollution, the opportunity cost of abating pollution in the form of reduced output, have to be estimated using specific techniques and serve several purposes. It’s a signal firms have to take into consideration when they decide upon their investment decisions. Shadow prices can also inform policymakers when they set policies. They can be used to assess policy ex ante by comparing the marginal benefits of environment policies with the cost they involve for private firms. These prices can be seen as benchmark for allowance price in emission market-based schemes or can be useful in designing optimal environmental tax schemes. The indicator can also be used ex post and can be considered as a policy indicator of pollution regulation and compliance to these regulations. More generally such prices are used each time there is a need to value pollution...

The relation between ports and their cities have evolved: it is no longer evident that well-functioning ports have automatically a net positive impact on the port-city. There are various trajectories and many ports and port-cities attempt to stimulate port-city development by a range of public policies. Yet, little is known about effectiveness of policies to promote performance of ports and port-cities. This paper aims at filling this gap, by assessing the effectiveness of port-city policies, within various policy areas including port development, port-city economic development, transportation, environment, research and development, spatial development and communication. This is done via a principal component analysis (PCA), based on a database constructed for the purpose of this paper with outcome variables and scores of policies for a set of 27 large world port-cities, that makes it possible to identify policies that are associated with effective policy outcomes and show patterns of related policy outcomes and policies.
