I develop a model of life-cycle portfolio choice with non-tradeable idiosyncratic labor income where the agent has an option to invest in human capital, for example through education. The inability to borrow against her human capital depresses the agent’s demand for equity, as she is concerned about being liquidity constrained when it is optimal to invest. The model has many predictions that ar...

This chapter analyzes reference-dependent consumption plans in a context of imperfect financial markets. Applications of prospect theory suggest that utility depends not only on consumption itself but also on gains and losses relative to prior consumption plans. By loss aversion, consumers prefer not to consume below planned levels, and by diminishing sensitivity, they prefer to take a sure los...

A stylized theory of money and central banking is added to a model of competitive equilibrium in asset markets to explain the determination of the general level of asset prices and interest rates. The cash-in-advance constraint provides a transactions demand for money, but this is not sufficient to guarantee the determinacy of the price level if liquidity is costless or the price level is uncer...

We study the effect of non-marketability on stock prices, and examine a unique repeated non-marketability constraint that lasts for less than one day in China. Chinese stock buyers face a one-day lockup and cannot sell their shares until the next trading day. Using the equity call warrants that are not subject to this trading constraint as a control, we provide evidence that non-marketability l...

THE LIQUIDITY TRAP-that awkward condition in which monetary policy loses its grip because the nominal interest rate is essentially zero, in which the quantity of money becomes irrelevant because money and bonds are essentially perfect substitutes-played a central role in the early years of macroeconomics as a discipline. John Hicks, in introducing both the IS-LM model and the liquidity trap, id...

This paper develops a sequential random matching model of asset trading to analyze how the extent of information about an asset that is available in the market can affect its tradeability. Liquidity traders are rational agents with higher impatience, which make optimal intertemporal consumption decisions given the trading constraints. Information asymmetries result in unexecuted trades. Agents ...

This paper examines monetary and fiscal policy through the estimation of a New-Keynesian dynamic general equilibrium model for Iran’s economy. In this New-Keynesian dynamic general equilibrium model, the consumers encounter the liquidity constraint and the firms face sticky prices, while they are changing them. In the model presented, a role is considered for both government spending and taxati...

Liquidity risk management ranks to key concepts applied in finance. Liquidity is defined as a capacity to obtain funding when needed, while liquidity risk means as a threat to this capacity to generate cash at fair costs. In the paper we present challenges of liquidity risk management resulting from the 20072009 global financial upheaval. We see five main regulatory liquidity risk management is...

This paper shows that future expected income uncertainty can have significant effects on saving levels in a simple model with a quadratic utility function in which consumers face potentially binding liquidity constraints. By interpreting saving as the option to consume in the future if income happens to be low and the liquidity constraint binds, I propose a theoretical framework for the existen...
