The evolution of cost-productivity and efficiency among US credit unions

Advances in information-processing technology have eroded the advantages of small scale and proximity to customers that traditionally enabled small lenders to thrive. Nonetheless, the membership and market share of US credit unions have increased, though their average size has also risen. We investigate changes in the efficiency and productivity of US credit unions during 1989–2006 by benchmarking the performance of individual firms against an estimated order-α quantile lying “near” the efficient frontier. We construct a cost analog of the Malmquist productivity index, which we decompose to estimate changes in cost and scale efficiency, and changes in technology. We find that cost-productivity fell on average across all credit unions but especially among smaller credit unions. Smaller credit unions confronted a shift in technology that increased the minimum cost required to produce given amounts of output. All but the largest credit unions also became less scale efficient over time.     

In- and out-of-sample specification analysis of spot rate models: Further evidence for the period 1982–2008

We review and construct consistent in-sample specification and out-of-sample model selection tests on conditional distributions and predictive densities associated with continuous multifactor (possibly with jumps) and (non)linear discrete models of the short term interest rate. The results of our empirical analysis are used to carry out a “horse-race” comparing discrete and continuous models across multiple sample periods, forecast horizons, and evaluation intervals. Our evaluation involves comparing models during two distinct historical periods, as well as across our entire weekly sample of Eurodollar deposit rates from 1982 to 2008. Interestingly, when our entire sample of data is used to estimate competing models, the “best” performer in terms of distributional “fit” as well as predictive density accuracy, both in-sample and out-of-sample, is the three factor Chen (Chen, 1996) model examined by Andersen, Benzoni and Lund (2004). Just as interestingly, a logistic type discrete smooth transition autoregression (STAR) model is preferred to the “best” continuous model (i.e. the one factor Cox, Ingersoll, and Ross (CIR: 1985) model) when comparing predictive accuracy for the “Stable 1990s” period that we examine. Moreover, an analogous result holds for the “Post 1990s” period that we examine, where the STAR model is preferred to a two factor stochastic mean model. Thus, when the STAR model is parameterized using only data corresponding to a particular sub-sample, it outperforms the “best” continuous alternative during that period. However, when models are estimated using the entire dataset, the continuous CHEN model is preferred, regardless of the variety of model specification (selection) test that is carried out. Given that it is very difficult to ascertain the particular future regime that will ensue when constructing ex ante predictions, thus, the CHEN model is our overall “winning” model, regardless of sample period.     

Evaluating foreign exchange market intervention: Self-selection,counterfactuals and average treatment effects

Estimating the effect of official foreign exchange market intervention is complicated by the fact that intervention at any point entails a “self-selection” choice made by the authorities and that no counterfactual is observed. To address these issues, we estimate the “counterfactual” exchange rate movement in the absence of intervention by introducing the method of propensity-score matching to estimate the “average treatment effect” (ATE) of intervention. To derive the propensity scores we estimate central bank intervention reaction functions. We estimate the ATE for daily official intervention in Japan over the January 1999–March 2004 period. This sample encompasses a remarkable variation in intervention frequencies as well as unprecedented frequent intervention towards the latter part of the period. We find that only sporadic and relatively infrequent intervention is effective.     

Asymmetric benchmarking in compensation: Executives are rewarded for good luck but not penalized for bad

Principal-agent theory suggests that a manager should be paid relative to a benchmark that removes the effect of market or sector performance on the firm's own performance. Recently, it has been argued that such indexation is not observed in the data because executives can set pay in their own interests; that is, they can enjoy “pay for luck” as well as “pay for performance.” We first show that this argument is incomplete. The positive expected return on stock markets reflects compensation for bearing systematic risk. If executives’ pay is tied to market movements, they can only expect to receive the market-determined return for risk-bearing. This argument, however, assumes that executive pay is tied to bad luck as well as to good luck. If executives can truly influence the setting of their pay, they will seek to have their performance benchmarked only when it is in their interest, namely, when the benchmark has fallen. Using industry benchmarks, we find significantly less pay for luck when luck is down (in which case, pay for luck would reduce compensation) than when it is up. These empirical results are robust to a variety of alternative hypotheses and robustness checks, and they suggest that the average executive loses 25–45% less pay from bad luck than is gained from good luck.     

Subsidiary debt,capital structure and internal capital markets

I study external debt issued by operating subsidiaries of diversified firms. Consistent with Kahn and Winton's [2004. Moral hazard and optimal subsidiary structure for financial institutions. Journal of Finance 59, 2537–2575] model, where subsidiary debt mitigates asset substitution, I find firms are more likely to use subsidiary debt when their divisions vary more in risk. Consistent with subsidiary debt mitigating the free cash flow problem, I find that subsidiaries are more likely to have their own external debt when they have fewer growth options and higher cash flow than the rest of the firm. Finally, I find that subsidiary debt mitigates the “corporate socialism” and “poaching” problems modeled in theories of internal capital markets.     

CEO pay and the Lake Wobegon Effect

The “Lake Wobegon Effect,” which is widely cited as a potential cause for rising CEO pay, is said to occur because no firm wants to admit to having a CEO who is below average, and so no firm allows its CEO's pay package to lag market expectations. We develop a game-theoretic model of this Effect. In our model, a CEO's wage may serve as a signal of match surplus, and therefore affect the value of the firm. We compare equilibria of our model to a full-information case and derive conditions under which equilibrium wages are distorted upward.     

Dirty work and the construction of identity. An ethnographic study of management accounting practices

This paper examines the processes by which identity work influences accounting and organisational practices. Analysing ethnographic material, we study how accountants engage in a struggle for recognition in a context where tensions emerge from the confrontation between idealised occupational aspirations and situated possibilities. To theorise this struggle we draw on Everett Hughes’s conceptualisation of a moral division of labour. Building on his concept of “dirty work”, we differentiate between the “unclean” and the “polluted”. Accountants have to perform tasks that are incompatible with the aspirational identities they claim; more than “boring”, these tasks become symbols of misrecognition. We call these unclean tasks. Yet even tasks that, in a more favourable context, would be associated with prestigious aspects of the job, can become degrading in specific situations. We call them polluted work. We highlight how trying to comply with a positively-anticipated role transition can help avoid unclean work yet generate more polluted work. Our analysis suggests that paying greater attention to symbolic differentiations between prestigious and shameful aspects of work can improve our understanding of accounting, identity work and organisational practices.     

Ontology-based e-assessment for accounting: Outcomes of a pilot study and future prospects

This article reports on a pilot of a novel ontology-based e-assessment system in accounting that draws on the potential of emerging semantic technologies to produce an online assessment environment capable of marking students’ free-text answers to questions of a conceptual nature. It does this by matching their response with a “concept map” or “ontology” of domain knowledge expressed by subject specialists. The system used, OeLe, allows not only for marking, but also for feedback to individual students and teachers about student strengths and weaknesses, as well as to whole cohorts, thus providing both a formative and a summative assessment function. This article reports on the results of a “proof of concept” trial of OeLe, in which the system was implemented and evaluated outside its original development environment (an online course in education being used instead in an undergraduate course in financial accounting. It describes the potential affordances and demands of implementing ontology-based assessment in accounting, together with suggestions of what needs to be done if such approaches are to be more widely implemented.     

An expectations-driven interpretation of the “Great Recession”

The boom-years preceding the “great recession” were a time of rapid innovation in the financial industry. We explore the idea that both the boom and eventual bust emerged from overoptimistic expectations of efficiency-gains in the financial sector. We treat the bankruptcy costs facing intermediaries in a costly state verification problem as a stochastic process, and model the boom-bust in terms of an unfulfilled news-shock where the expected fall in costs are eventually not realized. In response to a change in expectations only, the model generates a boom-bust cycle in aggregate activity, asset prices and leverage, and a countercyclical credit spread.     

On the determinants of “small” and “large” foreign exchange market interventions: The case of the Japanese interventions in the 1990s

During the past 30 years, central banks have often intervened in foreign exchange markets, and the magnitude of their foreign exchange market interventions has varied widely. We develop a quantitative reaction function model that renders it possible to examine the determinants of “small” and “large” interventions. We apply the model to analyzing the intervention policy of the Japanese monetary authorities (JMA) in the yen/U.S. dollar market during the period from 1991 through 2001. To this end, we use recently released official data on the foreign exchange market interventions of the JMA. We find that the JMA tended to conduct large interventions when the yen/U.S. dollar exchange rate drifted away from an “implicit target exchange rate.”     

Do they do it for the money?

Using a sample of all top management who were indicted for illegal insider trading in the United States for trades during the period 1989-2002, we explore the economic rationality of this white-collar crime. If this crime is an economically rational activity in the sense of Becker (1968), where a crime is committed if its expected benefits exceed its expected costs, “poorer” top management should be doing the most illegal insider trading. This is because the “poor” have less to lose (present value of foregone future compensation if caught is lower for them). We find in the data, however, that indictments are concentrated in the “richer” strata after we control for firm size, industry, firm growth opportunities, executive age, the opportunity to commit illegal insider trading, and the possibility that regulators target the “richer” strata. We thus rule out the economic motive for this white-collar crime, and leave open the possibility of other motives.     

Capital market imperfections and the theory of optimum currency areas

This paper studies how within- and cross-country capital market imperfections affect the welfare effects of forming a currency union. The analysis considers a bank-only world where intermediaries compete in Cournot fashion and monitoring and state verification are costly. The first part determines the credit market equilibrium and the optimal number of banks, prior to joining the union. The second part discusses the benefits from joining a currency union. A competition effect is identified and related to the added monitoring costs that banks may incur when operating outside their home country, through an argument akin to the Brander-Krugman “reciprocal dumping” model of bilateral trade. However, in our framework, whether joining a union raises welfare of the home country is ambiguous; it depends on the relative strength of “investment creation” and “intermediation diversion” effects.     

Is it the weather? Response

Kamstra, Kramer and Levi (KKL) in their comment seem to miss the main point of our paper. Many things are correlated with the seasons so it is difficult to distinguish between them when we try to explain the well-known summer winter pattern in stock returns. Finding an isolated seasonal affective disorder (SAD) effect without proper control variables does not disprove our point but strengthens it. To sidestep all of the issues they raise and take our point to the extreme, we show using plain vanilla regressions that the seasonal stock market pattern they attribute to SAD can also be “explained” by variables like ice cream consumption or airline travel. The new variations of SAD variables (“onset” and “incidence”) KKL propose in their recent work for North America are even more problematic than the original SAD variables. We find that these new SAD proxies are not significant in countries where according to KKL they should be: Canada and the United States.     

One monetary policy and 18 central bankers: The European monetary policy as a game of strategic delegation

This paper employs a multi-country delegation monetary policy model and argues that a decision-making mechanism based on the median voter theorem where intensity of preferences cannot play a role does not capture important aspects of policy setting in the European Monetary Union. Replacing the median voter mechanism with a less restrictive “weighted mean mechanism”, it is shown that strategic delegation can lead to a surprising degree of central bank inflation aversion. This finding supports the “The Twin Sister Hypothesis” and the perception of the European Central Bank implementing the policy of the Bundesbank rather than a more inflationary monetary policy.     

“Holier-than-thou” perception bias among professional accountants: A cross-cultural study

Theoretical conceptions of culture in accounting research are controversial, ranging from highly deterministic, quantified and componential perspectives (such as Hosfstede's five dimensional model) to those that suggest continual changes in cultural values brought about by forces of acculturation. This paper makes a contribution to cross-cultural accounting research by examining the influence of competing theoretical perspectives of culture and acculturation on “holier-than-thou” perception bias. “Holier-than-thou” perception bias leads to individuals perceiving themselves as acting more ethically than comparable others when confronted with ethically uncertain work-related behaviours. This study contributes to cross-cultural accounting research by surveying Australian and Indian professional accountants from big four accounting firms. We firstly seek to establish the prevalence of “holier-than-thou” perception bias in both cultural settings. Secondly, we examine the differential and competing influences of culture and acculturation on perceptions of accountants from the two countries on measures of this bias. Data was collected through a survey questionnaire administered to samples of senior accountants from the big accounting firms in Australia and India. The questionnaire comprised an auditor-client conflict and two whistle-blowing scenarios and used two questions to measure the magnitude of the bias. The results show that “holier-than-thou” perception bias exists among accountants within each of the two countries. However, the magnitude of the bias was not significant between the countries. The results support the theory of acculturation in big accounting firms. Our findings have implications for accounting research where the presence of “holier-than-thou” perception bias needs to be considered in cases where respondents are questioned on socially sensitive issues. The findings may be useful to accounting researchers, managers of multinational enterprises in general, and big-four accounting firms in particular. Our conceptual framework applied in this study is innovative and provides a template for assessing current controversies in cross-cultural accounting research.     

Money with partially directed search

Partially directed search replaces the total randomness of monetary search models. Agents choose whether to stay in their production location or visit other locations. Each visiting agent randomly chooses one shop among many in each location. As in random matching models, a commodity or fiat object can endogenously become money, but the details are richer and conform better with evidence: any commodity can be money; the “best” commodity is the most likely money; fiat money can totally crowd out commodity money in an asymmetric environment; going shopping is more likely than door-to-door sales. The model nests Walrasian equilibria.     

The future of the self-image of the human being in the Age of Transhumanism, Neurotechnology and Global Transition

In the present moment of cultural and political transition, one question seems to become the center of most other societal and civilizational questions: will the basic self-perception of the human being change under the influence of the new “neurotechnologies” and its accompanying ideologies like “Human enhancement” and “Transhumanism”? And if yes, how? Applied consciousness research is currently one-sidedly understood as brain research, and it is carried out mainly by the Natural Sciences under the influence of the “Economic–Technological Complex” and its relatively narrow interests. With its paradigmatic materialism determining the cultural spread of its temporary findings, it is already modifying our imaginary about what a human being is, what its rational self-determination can be, and how a “good society” can work. What is at stake with the change related to the findings of the new “consciousness technologies” is not only the principal socio-philosophical status of the human “self” or “I”, but also the related concepts of humanism, open societies, individualism and rationality. Thus, the new neurotechnologies and their “neurophilosophies” are currently in the process of profoundly influencing the very basics of our cultural self-understanding, grown over centuries. This article discusses some of the implications of this development within the greater picture of the current “global mindset change”.     

The optimal currency basket under vertical trade

This paper explores the theory of optimal currency basket in a small open economy general equilibrium model with sticky prices. In contrast to existing literature, we focus on an economy with vertical trade, where the currencies in the basket may play different roles in invoicing trade flow. In a simple two-currency basket, one currency is used to invoice imported intermediate goods and is called “import currency”, while the other currency is used to invoice exported finished goods and is called “export currency”. We find that the optimal weights of the import currency and the export currency depends critically on the structure of vertical trade. Moreover, if a country decides to choose a single-currency peg, the choice of pegging currency also depends on how other competing economies respond to external exchange rate fluctuations.     

Market concentration and the likelihood of financial crises

According to theory, market concentration affects the likelihood of a financial crisis in different ways. The “concentration-stability” and the “concentration-fragility” hypotheses suggest opposing effects operating through specific channels. Using data of 160 countries for the period 1970–2009, this paper empirically tests these indirect effects of financial market structure. We set up a simultaneous system in order to jointly estimate financial stability and the relevant channel variables as endogenous variables. Our findings provide support for the assumption of channel effects in general and both the concentration-stability and the concentration-fragility hypothesis in particular. The effects are found to vary between high and low income countries.     

Firm value,illiquidity risk and liquidity insurance

Our interest here concerns liquidity supply to firms. We first examine the relation between firm value and access to liquidity supply, and then we investigate the existence conditions and efficiency properties of financial contracts with a liquidity covenant in a continuous-time, infinite-horizon stochastic model of a repeated firm-investors relationship where the key problem is the mutual commitment between the two parties. To model this problem we consider liquidity supply as a stochastic “regulator mechanism” that prevents the firm’s ability to pay from falling below a predefined threshold (here the market fixed coupon), and we then apply recent developments in dynamic programming techniques for “regulated processes” to obtain a close form solution for the firm’s value. Our main finding is that efficient, i.e. actuarially fair and renegotiation-proof contracts emerge in the absence of perfect commitment as the firm and the investor can exert mutual threat of termination.
