Future of Irrigation and Drainage in Pakistan

The future of Pakistan’s agriculture depends on the future of its irrigation and drainage system, which currently faces major problems. Increasing water logging and salinity, overexploitation of fresh groundwater, low efficiency in delivering and use, inequitable distribution, unreliable delivery, and insufficient cost recovery are some of these problems. These problems, however, are only symptoms of a deeper problem—the treatment by the government of irrigation water as a public good. Such a treatment has caused inefficient pricing of water, misallocation of resources and widespread rent-seeking behaviour. The future strategy for irrigation and drainage will require a major change in the public sector’s approach. An efficient self-sustaining irrigation and drainage system can be achieved only by promoting market-determined incentives for improved management of the irrigation and drainage services and giving the private sector a greater stake in the system. The process could begin by developing commercially-oriented public utilities on a canal-command basis, developing suitable farmer organisations around distributaries/minors, formalising water rights, developing autonomous provincial water authorities, and developing provincial regulatory bodies for regulating public utilities, water rights, and groundwater resources.

A European research agenda for lifelong learning

It is a generally accepted truth that without a proper educational system no country will prosper, nor will its inhabitants. With the arrival of the post-industrial society, in Europe and elsewhere, it has become increasingly clear that people should continue learning over their entire life-spans lest they or their society suffer the dire consequences. But what does this future lifelong learning society exactly look like? And how then should education prepare for it? What should people learn and how should they do so? How can we afford to pay for all this, what are the socio-economic constraints of the move towards a lifelong-learning society? And, of course, what role can and should the educational establishment of schools and universities play? This are questions that demand serious research efforts, which is what this paper argues for

Europe’s New Post-Trade Infrastructure Rules. ECMI Policy Brief No. 20, 8 November 2012

After more than a decade of indecision, the EU is finally now set to implement a consistent regulatory architecture for clearing and settlement. Following the agreement on a European market infrastructure Regulation (EMIR), the European Commission has proposed harmonised rules for centralised settlement depositaries (CSDs), while the European Central Bank is moving forward with its plans for a central eurozone settlement engine. This paper analyses three components of the new post-trade infrastructure measures: 1) the regulatory framework for and supervision of central counterparties under the new EMIR legislation, 2) the authorisation requirements of trade repositories and 3) the draft CSD Regulation and the progress with the ECB’s Target 2 Securities project. It then discusses the impact of the new rules, and argues that, analogous to the unexpected impact of MiFID on trading infrastructures, a similar EMIR revolution may be on its way

Network Effects, Congestion Externalities, and Air Traffic Delays: Or Why All Delays Are Not Evil

We examine two factors that might explain the extent of air traffic delays in the United States: network benefits due to hubbing and congestion externalities. Airline hubs enable passengers to cross-connect to many destinations, thus creating network benefits that increase in the number of markets served from the hub. Delays are the equilibrium outcome of a hub airline equating high marginal benefits from hubbing with the marginal cost of delays. Congestion externalities are created when airlines do not consider that adding flights may lead to increased delays for other air carriers. In this case, delays represent a market failure. Using data on all domestic flights by major US carriers from 1988-2000, we find that delays are increasing in hubbing activity at an airport and decreasing in market concentration but the hubbing effect dominates empirically. In addition, most delays due to hubbing actually accrue to the hub carrier, primarily because the hub carrier clusters its flights in short spans of time in order to maximize passenger interconnections. Non hub flights at hub airports operate with minimal additional travel time by avoiding the congested peak connecting times of the hub carrier. These results suggest that an optimal congestion tax would have a relatively small impact on air traffic delays since hub carriers already internalize most of the costs of hubbing and a tax that did not take the network benefits of hubbing into account could reduce social welfare.

Peer effects, risk pooling, and status seeking: What explains gift spending escalation in rural China?

It has been widely documented that the poor spend a significant proportion of their income on gifts even at the expense of basic consumption. We test three competing explanations of this phenomenon—peer effect, status concern, and risk pooling—based on a census-type primary household survey in three natural villages in rural China and on detailed household records of gifts received on major occasions. We show that gift-giving behavior is largely influenced by peers in reference groups. Status concern is another key motive for keeping up with the Joneses in extending gifts. In particular, poor families with sons spend more on gift giving in proportion to their income than their rich counterparts, in response to the tightening marriage market. In contrast, risk pooling does not seem to be a key driver of the observed gift-giving patterns. However, we show that large windfall income triggers the escalation of competitive gift-giving behavior.ceremony, gift giving, Peer effect, risk pooling, social network, status seeking,

Estimating Historical Inequality from Social Tables: Towards Methodological Consistency

Research on long-term historical inequality has expanded to include previously neglected periods and societies, particularly in the global South. This is partly due to the resurgence of the social tables method in economic history, an approach which uses archival records to reconstruct income and wealth distributions in contexts where micro data is unavailable. This methodcan cause a downward bias in estimating inequality, but there is limited evidence of this bias in economic history. We collected a new data set of 108 historical social tables spanning over a 1000 years. We found that the compilers consistently made careful methodological choices that took data limitations into account. We found that the inequality estimates are not systematically related to the number of classes chosen or the size of the top class, but that choosing bottom classes that bundle together even small variations in income or wealth can introduce a downward bias to the inequality estimates. This drawback can be overcome by using methodological cohesion to mitigate the problem of limited information about the poorest classes in colonial archives

Medical Malpractice Litigation Under National Health Insurance: Essential or Expendable?

Identification of time-continuous models from sampled data is a long standing topic of discussion, and many approaches have been suggested. The Maximum Likelihood method is asymptotically and theoretically superior to other methods. However, it may suffer from numerical inaccuracies at fast sampling and it also requires reliable initial parameter values. A number of efficient and useful alternatives to the maximum-likelihood method have been developed over the years. The most important of these are State-Variable filters, combined with Instrumental Variable methods, including the simplified refined IV method. In this contribution we perform unpretentious numerical experiments to comment on these methods, and their mutual benefits.CADIC

The Paper Chase: Securitization, Foreclosure, and the Uncertainty of Mortgage Title

The mortgage foreclosure crisis raises legal questions as important as its economic impact. Questions that were straightforward and uncontroversial a generation ago today threaten the stability of a $13 trillion mortgage market: Who has standing to foreclose? If a foreclosure was done improperly, what is the effect? And what is the proper legal method for transferring mortgages? These questions implicate the clarity of title for property nationwide and pose a too-big-to-fail problem for the courts. The legal confusion stems from the existence of competing systems for establishing title to mortgages and transferring those rights. Historically, mortgage title was established and transferred through the public demonstration regimes of UCC Article 3 and land recordation systems. This arrangement worked satisfactorily when mortgages were rarely transferred. Mortgage finance, however, shifted to securitization, which involves repeated bulk transfers of mortgages. To facilitate securitization, deal architects developed alternative contracting regimes for mortgage title: UCC Article 9 and MERS, a private mortgage registry. These new regimes reduced the cost of securitization by dispensing with demonstrative formalities, but at the expense of reduced clarity of title, which raised the costs of mortgage enforcement. This trade-off benefitted the securitization industry at the expense of securitization investors because it became apparent only subsequently with the rise in mortgage foreclosures. The harm, however, has not been limited to securitization investors. Clouded mortgage title has significant negative externalities on the economy as a whole. This Article proposes reconciling the competing title systems through an integrated system of note registration and mortgage recordation, with compliance as a prerequisite to foreclosure. Such a system would resolve questions about standing, remove the potential cloud to real-estate title, and facilitate mortgage financing by clarifying property rights
