Ellsberg’s two-color experiment,portfolio inertia and ambiguity

Results in this paper relate the observation of an interval of prices at which a decision maker (DM) strictly prefers to hold a zero position on an asset (termed “portfolio inertia”) to the DM’s perception of the underlying payoff relevant events as ambiguous, as the term is defined in [Econometrica 69 (2001) 265]. The connection between portfolio inertia and ambiguity is established without invoking a parametric preference form, such as the Choquet expected utility or the max–min multiple priors model. This allows us to draw an observable distinction between portfolio inertia that may arise purely due to first-order risk aversion type effects, such as those which could arise even if preferences were probabilistically sophisticated, and portfolio inertia that involves ambiguity perceptions.     

Afriat’s Theorem and Samuelson’s ‘Eternal Darkness’

Suppose that we have access to a finite set of expenditure data drawn from an individual consumer, i.e., how much of each good has been purchased and at what prices. Afriat (1967) was the first to establish necessary and sufficient conditions on such a data set for rationalizability by utility maximization. In this note, we provide a new and simple proof of Afriat’s Theorem, the explicit steps of which help to more deeply understand the driving force behind one of the more curious features of the result itself, namely that a concave rationalization is without loss of generality in a classical finite data setting. Our proof stresses the importance of the non-uniqueness of a utility representation along with the finiteness of the data set in ensuring the existence of a concave utility function that rationalizes the data.     

A short proof of Deb’s Theorem on Schwartz’s rule

Schwartz in (Nous,7, 1972, Definition, 3) introduces a generalization of the Condorcet criterion, which is the classical approach to rational choice in the context of cycles, and he defines the Schwartz set. Deb (J Econ Theory 16:103–110, 1977) shows that the Schwartz set consists of the maximal elements according to the transitive closure of the asymmetric part of a binary relation corresponding to a choice process or representing the decision maker’s preferences. This note provides a short and simple proof of Deb’s theorem on the characterization of the Schwartz set.     

Afriat’s theorem for indivisible goods

We identify a natural counterpart of the standard GARP for demand data in which goods are all indivisible. We show that the new axiom (DARP, for “discrete axiom of revealed preference”) is necessary and sufficient for the rationalization of the data by a well-behaved utility function. Our results complement the main finding of Polisson and Quah (2013), who rather minimally modify the original consumer problem with indivisible goods so that the standard GARP still applies.     

Australia’s mining productivity decline: implications for MFP measurement

This paper investigates the mining sector’s poor productivity performance as measured by the growth accounting formula for multifactor productivity (MFP) index during the recent mining boom in Australia. We provide an alternative measure of productivity growth by estimating a translog variable cost function, with parameters that separate productivity growth due to technical change from that due to the effects of returns to scale, capacity utilisation and natural resource inputs. The results show that the average MFP growth in Australian mining based on the dual cost-function measure of technical change is 2 % over the sample period 1974–1975 to 2007–2008, rather than ?0.2 % from the published index. The difference arises because declining natural resource inputs, the effects of capacity utilisation and returns to scale have all reduced the ‘true’ MFP growth.

A conceptual framework for R&D strategic alliance assessment for Taiwan’s biotechnology industry

With the rapid development of technology, technology advancement is harder and harder with more and more risks in technology innovation, thus enterprises can’t carry out technology innovation program alone. The development of the emergence of the biotechnology industries provides valuable insights into the role of strategic alliances and networking that shaped the synergy between both industries. This paper provides a step by step methodology to evaluate R&D strategic alliances problem in Taiwan biotechnology Industry. The purpose of this paper is to formalize the choice of R&D strategic alliance modes for an individual multinational enterprise among Joint Venture, Franchise agreement, Licensing Agreement, Subcontract and Merger/acquisition. An illustrative example is presented to demonstrate the applicability of the proposed methodology. The proposed approach also provides a relatively simple and well suited decision making tool for this type of strategic decision making problem. This evaluation mode was identified as a workable method.     

Ambiguity on the insurer’s side: The demand for insurance

Empirical evidence suggests that ambiguity is prevalent in insurance pricing and underwriting, and that often insurers tend to exhibit more ambiguity than the insured individuals (e.g., Hogarth and Kunreuther, 1989). Motivated by these findings, we consider a problem of demand for insurance indemnity schedules, where the insurer has ambiguous beliefs about the realizations of the insurable loss, whereas the insured is an expected-utility maximizer. We show that if the ambiguous beliefs of the insurer satisfy a property of compatibility with the non-ambiguous beliefs of the insured, then optimal indemnity schedules exist and are monotonic. By virtue of monotonicity, no ex-post moral hazard issues arise at our solutions (e.g., Huberman et al., 1983). In addition, in the case where the insurer is either ambiguity-seeking or ambiguity-averse, we show that the problem of determining the optimal indemnity schedule reduces to that of solving an auxiliary problem that is simpler than the original one in that it does not involve ambiguity. Finally, under additional assumptions, we give an explicit characterization of the optimal indemnity schedule for the insured, and we show how our results naturally extend the classical result of Arrow (1971) on the optimality of the deductible indemnity schedule.     

Swimming on Land: Some Suggestions for Today’s Public Administration

In recent decades researchers have suggested various models for public administration organizations. These models and reforms, generally called New Public Management and Post-New Public Management, ignore the different developmental phases of public organizations, especially when dealing with non-Western countries. Instead of asking how public organizations should look, we suggest asking what should they do? To answer this question, we present several principles on the individual and organizational levels that can serve as a good compass for public managers. On the individual level, we maintain that public employees should focus on listening, helping and learning. On the organizational level, we advocate incorporating public policy with public administration, embracing core principles as opposed to trying to achieve ends, and returning public administration to its key role. These principles reinforce each other and thus can enhance the capability of public organizations.

The Fed’s TRAP

The article examines if US monetary policy implicitly responds to asset price booms. Using real-time data and a GMM framework we estimate a Taylor-type rule with an asset variable that captures phases of booms and busts in the real estate market. We identify quasi real-time booms and busts using an asset cycle dating procedure. Our analysis yields two main findings. Firstly, the Fed does implicitly respond to asset price booms in the real estate market. Secondly, these responses are typically pro-cyclic and their intensity changes over time.     

Reflections on PATCO’s Legacy: Labor’s Strategic Challenges Persist

The 1981 PATCO strike stands out as a symbol of union decline. The penchant to stigmatize PATCO detracts from important aspects of the union’s unorthodox strategy. Preparations for 1981 negotiations were coordinated by rank-and-file activists who referred to themselves as ‘choir boys’. An extensive mobilization network cultivated by the ‘choir boys’ contributed to cohesiveness and in effect democratized PATCO. The union’s effectiveness in building internal solidarity was its most notable accomplishment. Twenty-first-century labor-movement revitalization will require not only strong, creative leadership but also rank-and-file mobilization in the mold of PATCO’s ‘choir boy’ system. It is this type of grassroots activism that has the potential to promote an internal culture of militant action which can serve as the foundation for union growth.

The Union-Buster’s Toolkit

Anti-union campaigns conducted by specialists are widely employed and generally successful. Although they have been described in some detail, there has been little analysis as to how they are able to persuade workers to vote against their interests. This study proposes a model of the anti-union campaign in which different personality types gravitate into one of three camps: union supporters, union opponents, and swing voters. Anti-union messages evoke different reactions from each and are intended to drive a wedge between swing voters and union supporters. This model suggests several ways unions could make their campaigns more effective by taking personality differences into account.
