Synopsis It has been proposed that open thermodynamic systems will act to dissipate available energy gradients by self-organizing into
coherent structures that, with time, evolve and develop into nested hierarchies – panarchies – that adapt to internal and
external changes according to a characteristic adaptive cycle. This paper seeks to apply these ideas in the purely societal
realm by investigating the role of money in economic systems. Money represents the value embodied in goods; a value that is
separate from the exact nature of those goods. We suggest that money thereby liberates the ‘free value’ of economic desire
and that this free value has properties analogous to energy. The result is the self-organization of structures and systems
(‘econosystems’) that dissipate this ‘free value’. Econosystems act at different scales, and nested levels of econosystems
form a panarchy, having effects that can be observed. In particular, it appears that money facilitates the creation of relationships
between econosystem actors, increasing the connectedness of the econosystems that envelop those actors. We have identified
a phenomenon whereby freed social value (i.e. money) can aggregate, or pool, at a larger econosystem scale in structures such
as banks. These pools act as gradients that actors at the neighborhood scale can exploit for self-organization in the econosystem.
Thus, econosystem actors appear to be freed from thermodynamic constraints by using money as a means of self-organization.
However, because of these pools of aggregated social exergy, connectedness is increased at the larger scale of the econosystem.
The potential consequence of this dynamic is that money may act to push larger scale econosystems toward a state of heightened
vulnerability to collapse, while freeing smaller scale actors from apparent constraints. In this way, we propose that money
acts to skew information feedback loops between econosystem actors and larger scale structures such as economies and ecosystems.

Treating public policies as computable dynamic general equilibrium model specification errors offers computational and conceptional advantages for comparing models with data. The set of policies calculated to rationalize observed behaviors raises the substantive economic question whether, in any particular market, actual public policies sufficiently coincide with the model's behavior-rationalizing policies, or whether the model offers correct hypotheses about the determinants of demand and supply. As illustrations, public policies are calculated to rationalize, with respect to the stochastic neoclassical growth model, capital market behavior since WWII and labor market behavior in 1929–1950. One conclusion is that capital taxation drives a wedge between consumption growth and the expected pre-tax capital return, in the direction and amount predicted by the theory, and that capital taxation is the major intertemporal distortion in the postwar capital market. Second, a good theory of the Great Depression labor market must explain why measured MRS and MPL diverged so dramatically in 1929–1933 and why the wedge persisted. 相似文献

This article on the distribution of wealth among individuals in the United Kingdom presents recent work on the effects of including pension rights and the significance of sex, age and marital status. It describes the rationale for including the accrued rights in occupational and State pension schemes (funded or unfunded) and the methods of estimation used. For funded schemes the rights are valued as the accrued liability of the schemes to their members, and for unfunded schemes similar liabilities are hypothecated; these estimates of the value of accrued pension rights involve assumptions about future earnings and interest rates. The trend in average marketable wealth with age is upwards until advanced years when it slows down or slightly reverses. Adding occupational pension rights only slightly raises the trend for females but has a bigger effect for males. Adding State pension rights raises these upward trends until the age of 60 after which there is a decline. For marketable wealth on the average males are wealthier than females but less wealthy if single, divorced or widowed. Adding occupational pension rights improves the relative position of males; adding State pension rights cancels this out. The effect of marital status rises with both age and sex and therefore a detailed three-way analysis is made. For females widows are on average the wealthiest; for young males the married; for older males the single. Using Theil's coefficient of entropy for comparing the inequality of wealth, the addition of pension rights reduces inequality by two-thirds. Age accounts for only 6 percent of inequality for marketable wealth but for 31 percent if pension rights are included. 相似文献

In this paper we first explore the impact of nominal and real persistence on the transmission process of various shocks in an estimated DSGE model of the euro area. We then analyse its impact on optimal monetary policy and investigate the performance of various monetary policies when the policy maker is uncertain about the degree of nominal and real persistence. 相似文献

In this paper we develop and test theory regarding whether entrepreneurs contemplating starting a new venture account for the value of the option to defer the entry decision. While others have illuminated the theoretical applicability of real options theory to entrepreneurship, empirical evidence in this context is lacking. Consistent with predictions derived from real options theory, we find that high uncertainty in the target industry dissuades entry, and that the irreversibility of the entry decision moderates this relationship. Furthermore, we find that the irreversibility of the investment decision can be influenced by industry‐level, firm‐level and even individual‐level factors.

We propose a natural conjugate prior for the instrumental variables regression model. The prior is a natural conjugate one since the marginal prior and posterior of the structural parameter have the same functional expressions which directly reveal the update from prior to posterior. The Jeffreys prior results from a specific setting of the prior parameters and results in a marginal posterior of the structural parameter that has an identical functional form as the sampling density of the limited information maximum likelihood estimator. We construct informative priors for the Angrist–Krueger [1991. Does compulsory school attendance affect schooling and earnings? Quarterly Journal of Economics 106, 979–1014] data and show that the marginal posterior of the return on education in the US coincides with the marginal posterior from the Southern region when we use the Jeffreys prior. This result occurs since the instruments are the strongest in the Southern region and the posterior using the Jeffreys prior, identical to maximum likelihood, focusses on the strongest available instruments. We construct informative priors for the other regions that make their posteriors of the return on education similar to that of the US and the Southern region. These priors show the amount of prior information needed to obtain comparable results for all regions. 相似文献

Selection and execution of site decontamination projects is often best left to local authorities, in accordance with the subsidiarity principle, even though the budget for such projects is made available through a central authority. In this paper we suggest a practical budget allocation policy which a central authority can employ to allocate budgets to local authorities, while still optimising the central authority's environmental objective function. The procedure is fully consistent with the principle of decentralisation of responsibility for selection and execution of projects, and requires a minimum information exchange between local and central levels. Despite the information asymmetry between local and central levels, incentive compatibility problems can be (partially) prevented by choosing an appropriate evaluation mechanism. At the same time, the procedure is computationally effective and efficient, and can guarantee a fair budget allocation, making it easy to implement and politically acceptable. 相似文献

Tax incentives offered to attract firms engaged in foreign direct investment are often tied to performance requirements such as domestic content restrictions or adherence to environmental standards. The tax competition literature has repeatedly shown that competition between municipalities for mobile firms tends to drive taxes to low levels. One would expect a comparable result for burdensome performance requirements. Despite this, the evidence suggests that while taxes have indeed been driven down, performance requirements are as popular as ever. We explain this seeming conundrum by showing that in the presence of spillovers, binding performance requirements can act as a coordination device for firms. In equilibrium, municipalities choose performance requirements, which maximize joint surplus from investment. Competition between municipalities then transfers this surplus to firms via tax subsidies. 相似文献
