When an NGO Takes on Public Participation: Preparing a Plan for a Neighborhood in East Jerusalem

It is often non‐governmental organizations (NGOs) that promote empowered participation processes, and assume active roles in leading them. However, the ability of NGOs to take on such processes is under‐theorized. In many cases empowered participation involving NGOs takes place without political support from above (or with limited or conditional support). Our goal in this article is to use a case study of participatory planning in East Jerusalem to theorize processes of empowerment in an oppositional political environment. We argue that it is useful to analyze such processes of empowered participation through the concept of power. We describe the process of empowerment as a speculative process in which the NGO has to hedge two mediums of power: it has to build the power of the community to discuss its own goals; and it has to simultaneously manage the transfer of decision‐making power from government bodies to the community.     

Multi-unit auctions with budget limits

We study multi-unit auctions for bidders that have a budget constraint, a situation very common in practice that has received relatively little attention in the auction theory literature. Our main result is an impossibility: there is no deterministic auction that (1) is individually rational and dominant-strategy incentive-compatible, (2) makes no positive transfers, and (3) always produces a Pareto optimal outcome. In contrast, we show that Ausubel?s “clinching auction” satisfies all these properties when the budgets are public knowledge. Moreover, we prove that the “clinching auction” is the unique auction that satisfies all these properties when there are two players. This uniqueness result is the cornerstone of the impossibility result. Few additional related results are given, including some results on the revenue of the clinching auction and on the case where the items are divisible.     

The High-Volume Return Premium

The idea that extreme trading activity contains information about the future evolution of stock prices is investigated. We find that stocks experiencing unusually high (low) trading volume over a day or a week tend to appreciate (depreciate) over the course of the following month. We argue that this high-volume return premium is consistent with the idea that shocks in the trading activity of a stock affect its visibility, and in turn the subsequent demand and price for that stock. Return autocorrelations, firm announcements, market risk, and liquidity do not seem to explain our results.     

Health benefits: employer liability and the need for change

The cost of health care benefits has been rising much faster than overall inflation recently, and employees are increasingly dissatisfied with the programs being offered. This has left many human resources professionals searching for a better way. Against this background, attempts to increase employer liability pose serious threats. While some employers might consider abandoning health benefits to avoid this expanded liability, other alternatives may be more appealing and may be equally effective at limiting liability.     

Auditor Expertise and the Estimation of Dollar Error in Accounts

A major task that auditors undertake in formulating their audit opinion is to estimate the dollar error that might exist in accounts in light of their evaluation of internal control strengths and weaknesses. The research that has been undertaken to evaluate the quality of auditor performance on this task, however, has produced mixed results. The current study tries to overcome some theoretical limitations and measurement limitations that have undermined prior studies. Forty practising auditors rated their abilities on fourteen characteristics derived from a model of expertise. They then undertook an experiment where they judged the extent of dollar error that might exist in the inventories of a manufacturing company. They based their judgments on working papers provided to them that contained, among other information, an evaluation of the company's internal control system. An estimate of the 'true' dollar error in the inventories was calculated using a program that simulated the company's internal control and accounting system. This estimate was then used to calculate the accuracy of the auditors' judgments. Their ratings on the expertise characteristics were not related to their judgment accuracy. Their ratings were related, however, to their confidence in their judgment accuracy. Auditors who considered themselves more expert at the task were more confident in their judgment accuracy but they were, in fact, no more accurate than auditors who considered themselves to be less expert at the task.     

Keynes,investment, unemployment and expectations

In Keynes’ General Theory, investment determines effective demand, which determines unemployment and the labour market plays a negligible role. In New Keynesian models, labour market institutions determine the natural rate of unemployment and the speed at which unemployment adjusts to it. Investment is mostly ignored as a key variable behind the problem of high unemployment, despite a strong empirical association between investment and unemployment. We discuss the evolution of the ‘Keynesian’ model, and how in the process of domesticating the General Theory, the central relationship between unemployment and investment and the role of the state of confidence was bred out of the model. We then present some evidence of the centrality of investment and expectations to the long‐term evolution of unemployment in OECD countries. We also argue that recent results in finance, which find that individuals do not behave rationally and, moreover, that there may be no basis for rational calculation, provides support for Keynes’s notion that animal spirits play a central role in investment.
