Abstract In this paper we deal with the financial sector of CANDIDE 1.1. We are concerned with the determination of the short-term interest rate, the term structure equations, and the channels through which monetary policy influences the real sector. The short-term rate is determined by a straightforward application of Keynesian liquidity preference theory. A serious problem arises from the directly estimated reduced form equation, which implies that the demand for high powered money, but not the demand for actual deposits, is a stable function of income and interest rates. The structural equations imply the opposite. In the term structure equations, allowance is made for the smaller variance of the long-term rates, but insufficient explanation is given for their sharper upward trend. This leads to an overstatement of the significance of the U.S. long-term rate that must perform the explanatory role. Moreover a strong structural hierarchy, by which the long Canada rate wags the industrial rate, is imposed without prior testing. In CANDIDE two channels of monetary influence are recognized: the costs of capital and the availability of credit. They affect the business fixed investment and housing sectors. The potential of the personal consumption sector is not recognized, the wealth and real balance effects are bypassed, the credit availability proxy is incorrect, the interest rate used in the real sector is nominal rather than real, and the specification of the housing sector is dubious.

Coordination between individuals and between teams: the importance of insight in social dilemmas Coordination between individuals and between teams: the importance of insight in social dilemmas Marjolein de Best-Waldhober, Carsten K.W. De Dreu & Daan van Knippenberg, Gedrag & Organisatie, Volume 17, June 2004, nr. 3, pp. 187-203. In the context of a social dilemma, in which turn taking serves collective outcomes and only in the long run self-interest and personal outcomes, we studied long-term coordination, i.e. the alternation of sacrifice to achieve maximum joint outcomes. In particular, we studied the differences between individuals and dyads (two person groups) in coordination situations. Recent studies that compared individual with group negotiation seem to lead to opposite predictions. One paradigm predicts groups will perform better, because they outweigh individuals cognitively. The other paradigm predicts individuals will perform better, because they tend to have less fear and greed than groups. Results from the current study primarily support the first explanation. Dyads were less influenced by the complexity of the situation structure than individuals, because they have a better understanding of the long term structure of the situation.

We evaluated the impacts of entrainment and impingement at the Salem Generating Station on fish populations and communities in the Delaware Estuary. In the absence of an agreed-upon regulatory definition of “adverse environmental impact” (AEI), we developed three independent benchmarks of AEI based on observed or predicted changes that could threaten the sustainability of a population or the integrity of a community.Our benchmarks of AEI included: (1) disruption of the balanced indigenous community of fish in the vicinity of Salem (the “BIC” analysis); (2) a continued downward trend in the abundance of one or more susceptible fish species (the “Trends” analysis); and (3) occurrence of entrainment/impingement mortality sufficient, in combination with fishing mortality, to jeopardize the future sustainability of one or more populations (the “Stock Jeopardy” analysis).The BIC analysis utilized nearly 30 years of species presence/absence data collected in the immediate vicinity of Salem. The Trends analysis examined three independent data sets that document trends in the abundance of juvenile fish throughout the estuary over the past 20 years. The Stock Jeopardy analysis used two different assessment models to quantify potential long-term impacts of entrainment and impingement on susceptible fish populations. For one of these models, the compensatory capacities of the modeled species were quantified through meta-analysis of spawner-recruit data available for several hundred fish stocks.All three analyses indicated that the fish populations and communities of the Delaware Estuary are healthy and show no evidence of an adverse impact due to Salem. Although the specific models and analyses used at Salem are not applicable to every facility, we believe that a weight of evidence approach that evaluates multiple benchmarks of AEI using both retrospective and predictive methods is the best approach for assessing entrainment and impingement impacts at existing facilities.

Estimation of benchmark yield curve in developing markets is often influenced by liquidity concentration. Based on an affine term structure model, we develop a long run liquidity weighted fitting method to address the trading concentration phenomenon arising from horizon-induced clientele equilibrium as well as information discovery. Specifically, we employ arguments from models of liquidity concentration and benchmark security information. After examining time series behavior of price errors against our fitted model, we find results consistent with both the horizon and information hypotheses. Our evidence indicates that trading liquidity carries information effect in the long run, which cannot be fully captured in the short run. Trading liquidity plays a key role in long run term structure fitting. Markets for liquid benchmark government bond issues collectively form a long term equilibrium. Compared with previous studies, our results provide a robust and realistic characterization of the spot rate term structure and related price forecasting over time, which in turn help portfolio investment of fixed income and long run pricing of financial instruments.

Liquidation Cost

Few derived versions based on the classic bank run model have taken into account the framing effect of general lenders. The purpose of this study is to revisit the issue and discuss a model of bank run equilibrium combined with biased risk preference, which is applied to analyze how portfolio allocation and liquidity buffer in commercial banks are affected by liquidation cost and the reference point. The results suggest the condition on which the liquidity buffer of a particular bank should provide. Liquidation cost is positively correlated with the lower bound of liquidity buffer. The effect of the reference point on liquidity buffer partially depends on the slope of yield curve term structure. Higher reference point could typically cause a lower portion of long-term investment.
