We consider a two country growth model with international capital markets. These markets fund capital investment in both countries, and operate subject to a costly state verification (CSV) problem. Investors in each country require some external finance, but also provide internal finance, which mitigates the CSV problem. When two identical (except for their initial capital stocks) economies are closed, they necessarily converge monotonically to the same steady state output level. Unrestricted international financial trade precludes otherwise identical economies from converging, and poor countries are necessarily net lenders to rich countries. Oscillation in real activity and international capital flows can occur.

Creator: Green, Edward J. Series: Working paper (Federal Reserve Bank of Minneapolis. Research Department) Number: 509 Abstract:
Thinking regarding the privatization of state industries and enterprises in the former Comecon countries has tended to focus on the efficiency gains that would occur in the privatized sector. Based on the comparatively good performance and the rather rigid configuration of Comecon production institutions, the scope for such productivity gains seems small. Rather, productivity and innovation in the post-Comecon economies are likely to depend greatly on the emergence of new, initially small, entrepreneurial firms. The extent and form of privatization may affect these firms' prospects for success. How the privatized-firm and entrepreneurial sector will interact depends on public-finance considerations as well as on considerations of industrial organization.

This paper is about a useful way of taking account of frictions in asset pricing and macroeconomics. I start by noting that complete frictionless markets models have a number of empirical deficiencies. Then I suggest an alternative class of models with incomplete markets and heterogenous agents which can also accommodate a variety of other frictions. These models are quantitatively attractive and computationally feasible and have the potential to overcome many or all of the empirical deficiencies of complete frictionless markets models. The incomplete markets model can also differ significantly from the complete frictionless markets model on some important policy questions.

We investigate ex-ante efficient contracts in an environment in which implementation is costless. In this environment, standard debt contracts will typically not be optimal. Optimal contracts may involve defaults, even in states in which the borrower is fully able to repay. We then examine the welfare costs of arbitrarily restricting the set of feasible contracts to standard debt contracts. When model parameters are calibrated to realistic values, the welfare loss from exogenously imposing this restriction is extremely small. Thus, if the implementation costs are actually nontrivial (as seems likely), standard debt contracts will be (very close to) optimal.

Earlier researchers have found either no relation or a positive relation between the conditional expected return and the conditional variance of the monthly excess return on stocks when they used the standard GARCH-M model. This is in contrast to the negative relation found when other approaches were used to model conditional variance. We show that the difference in the estimated relation arises because the standard GARCH-M model is misspecified. When the standard model is modified allow for (i) the presence for seasonal patterns in volatility, (ii) positive and negative innovations to returns to having different impacts on conditional volatility, and (iii) nominal interest rates to affect conditional variance, we once again find support for a negative relation. Using the modified GARCH-M model, we also show that there is little evidence to support the traditional view that conditional volatility is highly persistent. Also, positive unanticipated returns result in a downward revision of the conditional volatility whereas negative unanticipated returns result in an upward revision of conditional volatility of a similar magnitude. Hence the time series properties of the monthly excess return on stocks appear to be substantially different from that of the daily excess return on stocks.

Creator: Chari, V. V. and Kehoe, Patrick J. Series: Working paper (Federal Reserve Bank of Minneapolis. Research Department) Number: 399 Abstract:
In this paper we analyze the constraints imposed by dynamic consistency in a model of optimal taxation. We assume that only distorting taxes are available to finance government consumption. Optimal fiscal policy requires the use of debt to smooth distortions over time. Dynamic consistency requires that governments at each point in time not have an incentive to default on the inherited debt. We consider policy functions which map the history of the economy including the actions of past governments into current decisions. A sustainable plan is a sequence of history-contingent policies which are optimal at each date given that future policies will be selected according to the plan. We show that if agents discount the future sufficiently little and if government consumption fluctuates then optimal sustainable plans yield policies and allocations which are identical to those under full commitment. We contrast our notion of dynamic consistency with other definitions.

Creator: Boyd, John H. and Graham, Stanley L. Series: Working paper (Federal Reserve Bank of Minneapolis. Research Department) Number: 398 Abstract:
This study estimates the effects of allowing bank holding companies (BHCs) to enter several lines of financial business not now permitted. A simulation technique is used to estimate the risk and return of hypothetical financial corporations after merger between a BHC and a large firm in each of these industries: securities, real estate, life insurance, property and casualty insurance, and insurance agencies. The study concludes that a merger between a BHC and a life insurance company may decrease the probability of bankruptcy for the merged firm relative to the BHC alone. This result does not hold true, however, for BHC mergers with firms in the other industries. In particular, BHC mergers with securities or real estate firms are found to increase the probability of bankruptcy.

Creator: Levine, David K. Series: Working paper (Federal Reserve Bank of Minneapolis. Research Department) Number: 388 Abstract:
Previous authors have argued that the optimal monetary policy is contractionary. If buyers value consumption substantially more than sellers, there is some randomness and informational constraints make asset trading useful, we show that there is an incentive compatible expansionary policy that dominates all incentive compatible contractionary policies.
