Using an analysis of micro-level entities in the market economy, this paper describes how soft constraint derives from interdependence among corporations, banks, and the government. Soft constraint is explained in relation to changes in concentrated shareholding ownership, the increasing dominance of the financial sector, and financial insurance. We conclude： 1） concentrated shareholding ownership and institutionalized soft budget constraint create sub-optimal allocation of resources in the market economy; 2） neoclassical microeconomic principles cannot explain the economic actions of organizations in the market economy and should be revised; 3） externalities associated with soft budget constraint have spread across the globe to become both the cause and primary effect of cyclic global financial and economic crises. Hence, the government, banks, and the corporate sector must work together to overhaul supervisory mechanisms. On a global level, governments must collaborate to build a new international economic order. Correcting imbalances in international reserve currencies and fortifying administration of cross-national economic organizations will mitigate the effects of soft budget constraint.展开更多

To start with, we show the first missing problem that money is “missing” if all agents expend their total budgets under the simple budget constraint. This problem shows that the simple budget constraint is inadequate as an objective monetary budget constraint. A deficiency of the simple budget constraint exists partly in that it does not reflect money circulation. To improve this deficiency, we incorporate the expenditure reflux formula into the simple constraint. The first missing problem is partially solved by the application of this reflux budget constraint, but another problem occurs. The new problem is that infinite expenditure is permitted under this constraint. This is the second missing problem. The second problem appears to be a variation of the solvability problem of the money circulation equation. Referring to the proof of the solvability, we incorporate a time irreversible disposal into the budget constraint. This irreversibility budget constraint brings us a provisional solution of the missing problems. However, it should not be called a perfect solution. We also examine the relationships between our research and two previous studies: the finance constraint and the cash-in-advance model.展开更多

Two equilibrium bidding strategies of each bidder are presented in these two conditions. By comparing them, the authors show that the equilibrium unit price bid in the presence of budget constraints will be less than that in the absence of budget constraints. The difference between the two equilibrium bids leads to the reduced revenue of the seller. And this difference will decrease as the number of the bidders increases.展开更多
