This paper explores how accounting consistency affects DSGE models. As many DSGE models descended from real business cycle models, I explore a simple labor-only RBC model and then a simple capital-and-labor RBC model with an exogenous external sector introduced. The conclusion reached in this...

In this paper, another factor that affects equity risk premium is derived from a simple classical monetary model, which basically adds back labor-leisure to a simple consumption-only consumption-based asset pricing model. If every present/future good is traded at time t=0, just as in traditional...

This paper discusses how real-life statistical analysis/inference deviates from ideal environments. More specifically, there often exist models that have equal statistical power as the actual data-generating model, given only limited information and information processing/computation capacity....

This paper explores dimensional analysis of production and utility functions in economics. As raised by Barnett, dimensional analysis is important in consistency checks of economics functions. However, unlike Barnett's dismissal of CES and Cobb-Douglas production functions, we will demonstrate...

In this paper, several flaws of the basic no-capital/labor-only New Keynesian model are discussed. Some flaws were left undiscovered because mass of varieties n in Dixit-Stiglitz aggregator is often considered as not affecting overall outcomes. Only when n=1 would ordinary results of the basic...

This paper provides a somewhat intertemporal microfoundation for IS-LM in an economy where there is a monopoly issuer of medium of exchange, money. The core microfoundation in this model comes from the Arrow-Debreu general equilibrium result that riskless interest rate may not be uniform across...

This paper presents a simple Ramsey-type model example where two infinitely-living agents have same utility function except for time preference, and shows that equilibrium is indeterminate that is to be interpreted as being non-existent. The issues regarding New Keynesian transversality...

This paper resolves the chainstore paradox by viewing each game of a monopolist against a single competitor as a sequential game. Every game is done under perfect and complete information. In this sequential game, with subgame perfection imposed, the number of sequential stages - even or odd -...

This paper argues that consumption-leisure tradeoff is difficult to include in several popular international trade models. The ones discussed are one of the Krugman's New Trade Theory models and the Eaton-Kortum trade model, and in these models, once consumption-leisure tradeoff is included,...

This paper provides a resolution of St. Petersburg paradox using the fact that budget/wealth of people is finite before the game, and that with infinite budget, the paradox obviously is meaningless. The paper also provides an alternate resolution
