Identity, morals, and taboos: beliefs as assets

We develop a theory of moral behavior, individual and collective, based on a general model of identity in which people care about “who they are” and infer their own values from past choices. The model sheds light on many empirical puzzles inconsistent with earlier approaches. Identity investments respond nonmonotonically to acts or threats, and taboos on mere thoughts arise to protect beliefs about the “priceless” value of certain social assets. High endowments trigger escalating commitment and a treadmill effect, while competing identities can cause dysfunctional capital destruction. Social interactions induce both social and antisocial norms of contribution, sustained by respectively shunning free riders or do-gooders.     

The institutional determinants of self-governance: a comment on Edward Stringham’s <Emphasis Type="Italic">Private Governance</Emphasis>

Many pages would be require to discuss Private Governance’s important contributions, so I focus on a relatively minor flaw: chapter 9 on moral beliefs is inconsistent with Stringham’s general treatment of private governance institutions as endogenous. Moral beliefs are essentially depicted as unchanging, but they actually are endogenous too. Individuals can pursue wealth through cooperative interaction, which requires trust, creating incentives to develop beliefs that encourage ethical and benevolent behavior. Alternatively wealth can be taken from others through force and/or guile. Beliefs to facilitate involuntary transfers also are institutionalized. For instance, in order to benefit from coercive wealth transfers “in good conscience,” recipients have incentives to see their victims as enemies to justify a moral “right” to transfers. Changing moral beliefs is costly, however, so they tend to be fixed in the short term. Once it becomes apparent that existing beliefs significantly conflict with an individual’s interests, she is forced to question those beliefs. The impetus for rationalizing new beliefs arises. The direction of evolution can be predicted with a rational decision-making model. To illustrate the endogeneity of moral beliefs, three institutional settings are examined: “dignity culture,” “honor culture,” and “victimhood culture”.     

Educational models for manpower development

In this paper a number of educational models are formulated and optimized. A single educational program multiperiod model is developed and optimized by means of dynamic programming. The type of results an educational administrator might obtain from this model and optimization are presented in an example which evaluates alternative future options. This single educational program model is extended to a multi-echelon model, allowing for the modifications to very realistic “compulsary-type” and “college-type” educational models. Linear programming generates the optimal decisions for the general multi-echelon multiperiod educational model.     

Intertemporal nonseparability,liquidity constraints,and seasonality of aggregate consumer expenditures: An empirical investigation

The paper proposes a simple framework for intertemporal nonseparability in consumer preferences. It relies on the distinction between consumption and expenditures. As only the latter are observable, a technology is postulated which gives current consumption as a weighted sum of current and past expenditures. The Euler equations of the modified maximization problem place restrictions on the autoregressive process of consumption and the real interest rate. Superimposing this model with an explicit seasonal model, results in a bivariate ARMA representation. Having investigated the issue of identification, the model is tested empirically by time series data on Austria. The main results of this investigation are. First, nonseparability is indeed an important element in characterizing aggregate expenditure behaviour. Current behaviour of households is therefore not exclusively forward looking but is committed by past expenditures. Second, this nonseparability is not due to habit formation but to a strong “durable component”. Third, Hall's orthogonality test presents no evidence for the presence of liquidity constrained households. Fourth, the misleading role of seasonal adjustment is documented. This raises serious doubts on the “excess sensitivity” and “smoothness” results which have been obtained with seasonally adjusted data.     

Rational demand and expenditures patterns under habit formation

This paper proposes a model in which habit formation is present in a relatively general but tractable way. The consumer's problem is transformed into a sequence of two-period Fisherian problems by introducing a “reduced utility function” to ensure full dynamic rationality of the consumer. By making preferences dependent on past real expenditure levels rather than past consumption bundles, it is possible to characterize the long-run behavior of the consumer. Stability analysis is performed. The cases of “immediate habit formation” and “delayed habit formation” are discussed.     

Testing Social Preferences for an Economic “Bad”: An Artefactual Field Experiment*

We test for social preferences over a commodity in an artefactual field experiment using the random price voting mechanism. Subjects are university staff members, and the commodity is water “contaminated” by a sterilized cockroach. Our results suggest that social preferences exist with respect to commodities and “bads”, supporting a more general utility framework for social preferences. Our empirical test allows for the coexistence of three social‐preference models; our results support the models of Fehr and Schmidt (1999) and Charness and Rabin (2002), but not the model of Bolton and Ockenfels (2000). Also, we find that incorporating social preferences improves the efficiency of majority‐rules voting.     

Stability with regime switching

The purpose of this paper is to analyze the stability of systems of piecewise continuous differential equations, and to apply the results to a disequilibrium economic model. The discontinuity problem appears in disequilibrium models because of the so-called “short-side” rule. The concept of Filippov solution makes it possible to analyze the dynamic evolution of such a model. This paper demonstrates that (i) stability conditions for each subsystem are neither necessary nor sufficient for overall stability, except in special cases such as a system of linear differential equations in R² with two regimes separated by a linear boundary; (ii) several sufficient conditions for overall stability with many regimes are available; and (iii) stability theorems with regime switching are useful for disequilibrium economic models with several regimes.     

A system of demand equations for Austria

This paper presents results of parameter estimations of a small system of demand equations for Austria. The functional form of the equations follows the log-linear specification well known as the “Rotterdam”-System. Using annual data from 1954 to 1977 we estimate the absolute price version for a rather aggregated system consisting of four sectors of consumption expenditures. Aitken estimation with and without linear restrictions is the adopted estimation method. Tests for the validity of the general linear restrictions axe performed employing the usual criteria. Relations among the test statistics are discussed. Taking into accountBeaton's [1972] argument of the appropriate use of likelihood ratio tests we present results also after iterating on the restricted error-covariance matrix. The question of negative semidefiniteness of the matrix of price coefficients is examined by inspection of its characteristic roots and the calculation of their approximated asymptotic covariance matrix. Finally, our results are confronted with such of other comparable studies.     

Anonymous social influence

We study a stochastic model of influence where agents have “yes” or “no” inclinations on some issue, and opinions may change due to mutual influence among the agents. Each agent independently aggregates the opinions of the other agents and possibly herself. We study influence processes modeled by ordered weighted averaging operators, which are anonymous: they only depend on how many agents share an opinion. For instance, this allows to study situations where the influence process is based on majorities, which are not covered by the classical approach of weighted averaging aggregation. We find a necessary and sufficient condition for convergence to consensus and characterize outcomes where the society ends up polarized. Our results can also be used to understand more general situations, where ordered weighted averages are only used to some extent. Furthermore, we apply our results to fuzzy linguistic quantifiers, i.e., expressions like “most” or “at least a few”.     

Market penetration of new products in segmented populations: A system dynamics simulation with fuzzy sets

The application of system dynamics methodology to the study of market penetration (diffusion) of new products offers considerable flexibility. The differential equations representing total (cumulative) sales need not be that restrictive as in those instances where solely mathematical tools are applied for their solutions. This paper first develops a mathematical formulation of “dynamic diffusion phenomena,” where the target population is not assumed to be constant in time. Besides incorporating the “marketing efforts” of the producer as an explicit variable, the model also gives due importance to the population characteristics affecting the diffusion phenomena. This is achieved by representing all variables and parameters in the differential equations as higher dimensional arrays. Then some basic properties of “fuzzy sets” are exploited to assign numerical values to the parameters. At the end, the problem is cast in a system dynamics setup for its solution. A computer solution with the help of a DYNAMO compiler for a hypothetical case is added to demonstrate the applicability of the ideas developed.     

Futures markets and commodity options: Hedging and optimality in incomplete markets

This paper examines the allocational roles of futures markets and commodity options in multi-good and multi-period economies. In a continuous-time model with time-additive utilities and homogeneous beliefs, trading in “unconditional” futures contracts, the market portfolio and a riskless asset gives any Pareto-optimal allocation. Individuals' optimal holdings of futures contracts in the continuous-time model are related to their consumption bundles and to their risk tolerances. It is shown that both hedging and “reverse hedging” behavior are possible. In the general model with discrete trading, options on portfolios of commodity options are shown to permit any unconstrained Pareto-optimal allocation.

A fire sale without fire: An explanation of labor-intensive FDI in China

China's labor-intensive industries are characterized by low technology and high competition. The massive inflow of FDI in China's labor intensive industries is inconsistent with the conventional wisdom that FDI should be more prevalent in technology-intensive and low competition industries. To explain this puzzle, we offer a “fire sale” hypothesis: facing severe financial constraints, Chinese private firms give up their equity to form joint ventures with foreign firms in order to obtain financing. Using the garment industry as an example, we find that among domestic firms, the financial constraint index is highest for private firms and lowest for state-owned firms. We further estimate a probit model of joint-venture decisions by private firms. Our results suggest that those private firms with greater financial constraints are more likely to seek foreign joint ownership. The effect of financial constraints on joint venture decision is both statistically and economically significant.     

Real estate price and heterogeneous investment behavior in China

We study the dynamic link between real estate prices and firms' investment behaviors in China using a new Keynesian dynamic stochastic general equilibrium model. The model features heterogeneous production sectors in which private firms face discriminatory borrowing constraints while state-owned firms are not. Fitted to China's quarterly data from 2005Q3 to 2014Q4, the quantitative general equilibrium model enables us to identify the driving forces behind and the macroeconomic variables interacting with land price. It confirms the existence of the “collateral channel” in the private sector without bearing the potential endogeneity problems in empirical studies. More importantly, we identify a “crowding out” channel between private and state-owned firms caused by discriminatory financial constraints. The “crowding out” channel implies a negative relationship between real estate prices and the investment of state-owned firms, which has been documented in empirical research but short of explanation so far.     

An empirical database for a general equilibrium model of the European Communities

We document the main features of a database that has been constructed for use in an applied general equilibrium model. The model is designed to evaluate policies of the European Community (EC), including membership. The database includes each of the major members of the EC in the 1970's: Germany, France, Italy, the Netherlands, Belgium, the United Kingdom, Denmark and Ireland. It also includes three further trading regions: the United States, Japan and a residual Rest of World. Four aspects of our database are documented. The first is the collection and use of “raw data” from a number of sources for 1975. The second aspect is the generation of a multi-year database, with 1975 serving as a “reference year” for temporal updates to more recent years. The third aspect is the application of the database to the calibration of a “generic” general-equilibrium trade model. The final aspect is the use of the database to study the historical accession of the United Kingdom to the EC.     

Options and strategies for fiscal consolidation in India

This paper uses a multi-region dynamic stochastic general equilibrium (DSGE) model to study options and strategies for fiscal consolidation in India. The challenge for India is how to put public finances on a more sustainable footing while preserving the potential for high growth and attenuating the adverse consequences on the needy. We analyze the macroeconomic implications of three fiscal consolidation scenarios. A “benchmark” case based on authorities' intentions that reduces government consumption, general transfers, and strengthens consumption tax collection; a “growth-friendly” that reallocates the savings to more public investment; and a “social-friendly” scenario that equally reallocates the savings between more public investment and more transfers to households excluded from the financial system. The simulations indicate that fiscal consolidation yields considerable long-term benefits and also entails output costs in the near term. Growth outcomes are better under the growth-friendly and social-friendly scenarios. These consolidation scenarios alone are not enough to maximize net gains for India. Other factors, such as the pace of consolidation, the combination with structural reforms and external economic conditions, play a critical role in the success of fiscal consolidation.     

THE TREATMENT OF EDUCATION IN NATIONAL ACCOUNTING1

It is argued that the conventions of an accounting system, such as the S.N.A., are a matter of convenience. The treatment of education as a current expenditure, instead of as a form of capital formation, derives from the Keynesian system, and is not appropriate for dynamic problems of developing countries, where weaknesses in education are often the main “bottleneck” in the process of development. In such countries, expenditure on education clearly yields its benefits mainly in the longer run. To treat this as a consumption item biases policy in the direction of using financial resources for fixed capital rather than human investment, and may cause aid agencies to penalize countries which expand their educational systems. A similar problem arises on other expenditures such as health, but the case for treating them as investment is not so strong. To treat educational expenditure as part of capital formation logically requires two major changes. First education needs to be removed from private and public consumption, and for this purpose a fairly broad definition of what is education should be used. Secondly, the stock of educational capital should be valued. The valuation problems are, however, severe. Variations in cost components make historic cost of little value as a yardstick, and calculations of future returns are fraught with difficulties. Using replacement costs, which seems the best method, involves the construction of education profiles in physical terms which can then be valued by present or by standardised costs. The depreciation of human capital through mortality and retirement can be allowed for by applying national average rates to these physical profiles. Switching educational expenditure from current to capital accounts involves no serious practical problem. However, although there should logically be an allowance for depreciation on human capital, this is not recommended; single monetary measures of educational stock are not very meaningful, and this would involve changing the definition of “net” aggregates. Development of statistics of educational stocks and flows in physical terms—the beginnings of “demographic accounting” fully integrated with the rest of national accounting—is strongly advocated.     

Social Welfare Functionals on Restricted Domains and in Economic Environments

Arrow's “impossibility” and similar classical theorems are usually proved for an unrestricted domain of preference profiles. Recent work extends Arrow's theorem to various restricted but “saturating” domains of privately oriented, continuous, (strictly) convex, and (strictly) monotone “economic preferences” for private and/or public goods. For strongly saturating domains of more general utility profiles, this paper provides similar extensions of Wilson's theorem and of the strong and weak “welfarism” results due to d'Aspremont and Gevers and to Roberts. Hence, for social welfare functionals with or without interpersonal comparisons of utility, most previous classification results in social choice theory apply equally to strongly saturating economic domains.     

新兴经济体国家城镇化发展对碳排放影响的比较研究

新兴经济体十六国是重要的发展集团,由“金砖五国”和“新钻十一国”组成,高效低碳的城镇化是其进一步提升在全球经济发展中增量贡献的动力保障。借助EKC模型和STIRPAT模型,分别研究这两个国家集团城镇化发展与碳排放量之间的关系以及城镇化对碳排放的影响。研究结果表明:在二者的关系方面,新兴经济体国家的城镇化水平与碳排放量呈现出微弱的倒“U”型关系,其中,“金砖五国”已经跨过倒“U”型曲线的拐点,而“新钻十一国”则处于拐点前期;在城镇化对碳排放的影响方面,城镇化发展对“新钻十一国”碳排放量的影响大于“金砖五国”;城镇化水平越高的国家,碳排放量越大,但随着工业化水平的提升和产业结构的优化升级,碳排放量逐步降低。     

Permanent On-The-Spot Job Creation—The Missing Keynes Plan for Full Employment and Economic Transformation

The paper rejects the conventional view that Keynes had an aggregate demand approach to full employment. Instead, it proposes that he advocated a very specific labor demand targeting approach that would be implemented both in recessions and expansions. Modern policies, which aim to “close the demand gap” between current and potential output are inconsistent with Keynes's work on theoretical and methodological grounds. There is considerable evidence to suggest that a permanent program for direct or (in his words) “on-the-spot” job creation is the missing Keynes Plan for full employment and economic transformation. The current crisis presents the social economist with a unique opportunity to set fiscal policy straight along the original Keynesian lines. The paper suggests what specific form such a policy might take.
