We consider a two-sector infinite horizon economy with a fractional cash-in-advance constraint on consumption expenditures. This formulation allows us to consider a steady-state velocity of money that is strictly greater than one and, therefore, provides a more plausible framework than the standard formulation in which all the consumption purchases are paid cash. We prove that the steady state is bound to be indeterminate and multiple equilibria occur when the share of the liquidity constraint is low enough and that a capital-intensive investment good or a strongly capital-intensive consumption good improve considerably the scope for indeterminacy. As a consequence, we show that without any restriction on the elasticity of intertemporal substitution in consumption, multiple equilibria might occur if the velocity of money is greater than a critical bound that is compatible with empirical estimates. 相似文献
We analyze the coordination problem of agents deciding to join a group that uses membership revenues to provide a discrete public good and excludable benefits. The public good and the benefits are jointly produced, so that benefits are valued only if the group succeeds in providing the public good. With asymmetric information about the cost of provision, the static membership game admits a unique equilibrium and we characterize the optimal membership fee. We show that heterogeneity in valuations for the excludable benefits is always detrimental to the group. However, in a dynamic contest in which heterogeneity arises endogenously (returning members receive additional seniority benefits at the expense of junior members), we show that, in the ex-ante optimal contract, offering seniority benefits is beneficial for the group, despite the heterogeneity in valuations created. 相似文献
Even though the channelling of equity capital from savers to listed firms is one of the primary functions of a stock market,
not much effort has been devoted to the problem of measuring the phenomenon. External equity financing, traditionally associated
with the issue of new shares, depends also on the sale of already issued shares. This additional form of collection of equity
capital becomes relevant when the firms of the market are connected by cross-shareholdings (as in Japan): the phenomenon of
equity carve-out is a relevant example of equity financing obtained through the sale of existing shares. The paper presents
a model for computing the equity capital raised by companies listed in a given stock exchange over a specified period of time,
which is non trivial when firms are connected by cross-shareholdings. A numerical computation of the net amount of equity
financing in the Tokyo Stock Exchange in the period 1971–1992 is reported: it shows that the net (or true) measure is significantly
different and, in most cases, lower than the conventional one. 相似文献
This paper aims to aid our understanding of the emergence of accounting as a control instrument in complex proto-industrial settings, through its perceived capacity of mirroring the production process. The paper starts off from an archival document, the 1586 deliberation by the Venetian Senate, which imposed on the Arsenal a stocktaking to be conducted every three years, and ad hoc galley production accounts to be kept in double entry format, where the passage of materials and work-in-process between units were recorded both in physical quantity and value. In this deliberation the Venetian Senate was clearly posing explicitly the problem of costing and the efficient use of resources within the Arsenal. Until then, the Senate controlled this organisation only by limiting the funds allocated to activities (wages, oars, 'stuffs') without entering into the substance of the operations. Two interrelated investigations are carried out. First, a content analysis of the 1586 document is made. Second, the question of its 'impact' on the Arsenal's actual accounting practices is addressed. In a 1633 Report by Alvise Molin, a magistrate of the Republic, some elements of the 1586 deliberation seem to surface, insofar as a quite sophisticated calculation of the production costs of galleys is provided. In this sense it might well be that the notion of cost emerged as a sort of 'accidental by-product' of the Senate's efforts aimed at introducing tighter forms of control on the Arsenal. 相似文献
A general class of models for derivative pricing with stochastic volatility is analyzed. We include the possibility of jumps for the paths of the asset's price and for those of its volatility. We also consider the case of correlation between the process of the asset's price and that of its volatility. In this way we are able to give a unifying view on most of the models studied in the literature. We will examine theoretical issues related to the market price of volatility risk, the equivalent martingale measures and the possibility of obtaining a numerically tractable formula for contingent claim pricing. Finally, we propose some methodologies to test the behavior of stochastic volatility models when applied to market data. 相似文献
Bayesian optimal experiments that maximize the information gained from collected data are critical to efficiently identify behavioral models. We extend a seminal method for designing Bayesian optimal experiments by introducing two computational improvements that make the procedure tractable: (1) a search algorithm from artificial intelligence that efficiently explores the space of possible design parameters, and (2) a sampling procedure which evaluates each design parameter combination more efficiently. We apply our procedure to a game of imperfect information to evaluate and quantify the computational improvements. We then collect data across five different experimental designs to compare the ability of the optimal experimental design to discriminate among competing behavioral models against the experimental designs chosen by a “wisdom of experts” prediction experiment. We find that data from the experiment suggested by the optimal design approach requires significantly less data to distinguish behavioral models (i.e., test hypotheses) than data from the experiment suggested by experts. Substantively, we find that reinforcement learning best explains human decision-making in the imperfect information game and that behavior is not adequately described by the Bayesian Nash equilibrium. Our procedure is general and computationally efficient and can be applied to dynamically optimize online experiments.
Schumpeter argued that boom and bust cycles are inherent to the rise of innovation and constitute an unavoidable consequence of the way the capitalist system reacts to the emergence of a wave of innovations. This contribution aims to describe Schumpeterian economic development in a ‘monetary theory of production’ framework, emphasizing the crucial role played by credit creation, conceived as ‘the monetary complement’ of innovation. By adopting a stock flow consistent analytical approach, we analyze both the structural change process triggered in the real economy by the emergence of innovation, and the monetary dynamics arising during the various stages of the development process. 相似文献
I examine how an important attribute of financial reporting quality, i.e., accounting conservatism, affects the sensitivity of corporate bond returns to changes in the value of equity (i.e., the hedge ratio). The correlation between stock and bond returns (co‐movement) is a fundamental input for asset allocation decisions as it determines the diversification benefits of bonds relative to equities within an investment portfolio. According to structural models of credit risk, co‐movement should be generally positive, but lower when the risk of wealth transfers from bondholders to shareholders is severe. I find that firms that report conservative earnings and use covenants in their bond contracts exhibit on average stronger co‐movement. This result is consistent with conservatism providing bondholders with a credible and contractible signal that improves monitoring, thus preventing wealth transfers. 相似文献
Starting from the recent quest to investigate the human side of organizational sustainability, this study applies a variety of regression analyses to investigate the effects of Lean Operations, High Involvement Work Practices, and management behaviors on occupational safety. It tests and finds support for the hypotheses that Lean Production systems, High Involvement Work Practices, and two specific management behaviors—workers’ capability development (coaching and teaching of workers) and empowerment (autonomy and participation of workers in developing their own job standards)—positively affect occupational safety. Furthermore, empowering behaviors positively moderate the effect of Lean Operations on workers’ safety. The study bridges sustainable operations literature with theories related to the ethical side of safety management, sustainable HRM, ethical leadership, and empowerment. In doing so, it contributes to the understanding of occupational safety as constitutive aspect of organizational sustainability. 相似文献
