A Classical Model Of Speculative Asset Price Dynamics, Sabiou M. Inoua, Vernon L. Smith Dec 2022

A Classical Model Of Speculative Asset Price Dynamics, Sabiou M. Inoua, Vernon L. Smith

ESI Working Papers

In retrospect, the experimental findings on competitive market behavior called for a revival of the old, classical, view of competition as a collective higgling and bargaining process (as opposed to price-taking behaviors) founded on reservation prices (in place of the utility function). In this paper, we specialize the classical methodology to deal with speculation, an important impediment to price stability. The model involves typical features of a field or lab asset market setup and lends itself to an experimental test of its specific predictions; here we use the model to explain three general stylized facts, well established both empirically and …


Perishable Goods Versus Re-Tradable Assets: A Theoretical Reappraisal Of A Fundamental Dichotomy, Sabiou M. Inoua, Vernon L. Smith Jan 2022

Perishable Goods Versus Re-Tradable Assets: A Theoretical Reappraisal Of A Fundamental Dichotomy, Sabiou M. Inoua, Vernon L. Smith

ESI Working Papers

Although various typologies of goods are commonly adopted in economics, one stood out in market experiment results contrasting market stability and efficiency with market instability: non-durable, or perishable, goods (Smith, 1962) versus durable re-tradable assets (Smith et al., 1988; Dickhaut et al., 2012; S. D. Gjerstad et al., 2015). This dichotomy of goods also proved central for understanding macroeconomic instability more broadly: about 75% of consumer spending is bought for final consumption, and is a rock of stability; instability arises from the other 25% re-tradable goods, most prominently, houses (S. D. Gjerstad & Smith, 2014). In this chapter, we revisit …
