Trade and wage inequality: Are they related?

The objective of this paper is to investigate the relationship between net exports and wage inequality in the U.S. The short- and long-run analyses of the U.S. trade and wage data are undertaken. Cointegration test results indicate that net exports and wage inequality are related in the long run. The main contribution of this paper lies in its focus on the short-run investigation of the relationship between net exports and wage inequality. This investigation was conducted using the vector error correction (VEC) testing framework. Contrary to the prevailing view, the VEC test results indicate that trade has no statistically significant impact on wage inequality in the U.S. Instead, the empirical evidence shows a negative causal impact of wage inequality on net exports.     

The Babu and the Boxwallah: Managerial Incentives and Government Intervention in a Developing Economy

In developing economies a firm's strategy is directed more often at the government than at other competing firms. As an initial step towards modeling such interactions this paper considers a situation where a government confronts a monopoly. The latter chooses price and maximizes profit and the former chooses a tax rate and maximizes tax revenue. The government and the monopoly can delegate the final decision-making to, respectively, a bureaucrat and a manager. The incentive equilibrium of the model is characterized. It is shown that this kind of industrial setting is likely to exhibit greater inefficiencies than that which arises in standard models.     

QUANTITY VERSUS PRICE IN A HOMOGENEOUS PRODUCT DUOPOLY*

In a simple homogeneous product setting, the paper looks at the debate on whether firms should choose quantity or price as their strategic variable. It examines a two-stage game between firms with symmetric costs in which the firms choose the strategic mode of operation in the first period and then, in the second period, price or output are chosen simultaneously according to the mode chosen in the first stage. In this game it is possible to have two Nash equilibria where either both play in quantities or both play in prices. One firm choosing price and the other quantity can never be a Nash equilibrium in the two-stage game. Both choosing quantity is always a Nash equilibrium. Both choosing prices may be a Nash equilibrium only in some situations: the structure of the cost functions decides this issue.     

EXCHANGEABLE DEBT CALLS AND SECURITY RETURNS

Exchangeable calls are not convertible into the calling firm's common stock but into the common stock of a target firm in which the calling firm has an ownership position. In addition to reducing leverage, exchangeables change the asset composition of the calling firm through the divestiture of the calling firm's ownership stake in the target firm. In contrast to the evidence on convertible calls, our findings indicate that announcements of exchangeable debt calls are not associated with an abnormal capital loss for the calling firm shareholders. For target firms, announcements of exchangeable calls reduce shareholder wealth. A lower probability of takeover resulting from diffusion of ownership concentration of the target firm's common stock may contribute to this result.     

Optimal Growth with Public Capital and Public Services

We characterize optimal economic growth in an endogenous growth model in which production requires public capital (a stock) and public services (a flow) in addition to private capital and labor. We analyze the comparative static effects of changes in the fundamental technological and preference parameters of the model on the optimal values of several variables, such as the optimal rate of growth and the optimal allocation of resources among consumption, the provision of public services, and investment in public and private capital. We show that the general optimal path converges in finite time to the balanced growth optimal path. We relate our paper to important contributions to the existing literature by obtaining them as special cases of our model.     

Bid-ask Spreads, Trading Volume and Volatility: Intra-day Evidence from the London Stock Exchange

This paper examines intra-day variations in the bid-ask spread, volatility and volume for stocks traded on the London Stock Exchange. The data set used consists of quote and transactions data for a large sample of 835 stocks traded during the first quarter of 1991. The focus of the study is twofold; first, is to document a number of stylized facts regarding the intra-day behaviour of spread, trading volume, volatility etc. Second, the paper tests some predictions of two theoretical models of intra-day behaviour: the Admati and Pfleiderer and the Brock and Kleidon models. In addition, the paper also studies qualitatively the intra-day behaviour of several variables of interest including volume per transaction, transactions per fifteen-minute interval and spreads/trading volume for stocks of differing liquidity. The results suggest that the bid-ask spread is wide at the open, constant through the day and rises slightly at the close. Trading volume, in contrast is not highest at the open and the close. Volatility, based on the mid-point of the inside spread, shows a U-shaped pattern. Volume per transaction, in contrast, is fairly constant throughout the day. Further, the intra-day trading volume pattern differs for liquid and illiquid stocks. The results provide mixed support for current theoretical models of intra-day behaviour of spread, volume and volatility on the London Stock Exchange     

Fiscal policy, long‐run growth, and welfare in a stock‐flow model of public goods

Abstract.  We introduce public capital and public services as inputs in an endogenous growth model. We show that the growth rate depends on the apportionment of tax revenues between the accumulation of public capital and the provision of public services. When public spending is financed by proportional income taxes, the growth rate, the level of public spending as a proportion of GDP, the level of investment in public capital as a proportion of total public spending, and the level of private investment as a proportion of total private spending all are lower in the equilibrium outcome than in the optimal outcome.

Endogenous growth, welfare and budgetary regimes

Within an optimizing endogenous growth model with productive public capital and government debt, we derive and characterize on the balanced growth path a set of welfare-maximizing fiscal rules under different budgetary regimes. It is shown that optimal fiscal policy depends on the specific budgetary stance considered.
