Integrating the Concepts of Global Freedom: Economics versus Society

Abstract. The paper carries out a context specific debate on why the real sector of the economy is important to look into to establish a framework of effective development. While doing that the paper highlights that the economic policy in the real sector is to be complemented by intervening in the progress of the society by developing social, political and legal institutions. This paper presents a post Washington consensus intellectual debate that eventually made the Prelog for first Millenium Development Goals (MDGs) and now Sustainable Development Goals (SDGs).Keywords: Role of economics, Relation of economics to social values, Sociology of economics.JEL.

Mergers, Litigation and Efficiency

We consider antitrust enforcement within the adversarial model used by the United States. We show that, under the adversarial system, the Antitrust Authority may try to prohibit mergers also in those cases in which litigation is inefficient. Even if market concentration and technological disadvantages lead to a significant welfare reduction after merger, from society’s perspective the agency’s lawsuit may be inefficient. We can show that these inefficiencies may be aggravated if the takeover is hostile

Eminent Domain Versus Government Purchase of Land Given Imperpect Information About Owners' Valuation

Governments employ two basic policies for acquiring land: taking it through exercise of their power of eminent domain; and purchasing it. The social desirability of these two policies is compared in a model in which the government's information about landowners' valuations is imperfect. Under this assumption, the policy of purchase possesses the market test advantage that the government obtains land only if an owner's valuation is low enough that he is willing to sell it. However, the policy suffers from a drawback when the land that the government needs is owned by many parties. In that case, the government's acquisition will fail if any of the owners refuses to sell. Hence, the policy of eminent domain becomes appealing if the number of owners of the land is large. This conclusion holds regardless of whether the land that the government seeks is a parcel at a fixed location or instead may be located anywhere in a region.

Endogenous Growth, Backstop Technology Adoption and Optimal Jumps

We study a two-phase endogenous growth model in which the adoption of a backstop technology (e.g. solar) yields a sustained supply of essential energy inputs previously obtained from exhaustible resources (e.g. oil). Growth is knowledge-driven and the optimal timing of technology switching is determined by welfare maximization. The optimal path exhibits discrete jumps in endogenous variables: technology switching implies sudden reductions in consumption and output, an increase in the growth rate, and instantaneous adjustments in saving rates. Due to the positive growth e¤ect, it is optimal to implement the new technology when its current consumption bene.ts are substantially lower than those generated by old technologies.Backstop technology, Discrete jumps, Endogenous growth, Exhaustible resources, Optimal Control

Arbitrage, market definition and monitoring a time series approach

This article considers the application to regional price data of time series methods to test stationarity, multivariate cointegration and exogeneity. The discovery of stationary price differentials in a bivariate setting implies that the series are rendered stationary by capturing a common trend and we observe through this mechanism long-run arbitrage. This is indicative of a broader market definition and efficiency. The problem is considered in relation to more than 700 weekly data points on gasoline prices for three regions of the US and similarly calibrated simulated series. The discovery of a single common trend is consistent with competitive pricing and a broad market definition, but the finding of a single weakly exogenous variable affects this conclusion

Tax Policy and Human Capital Formation with Public Investment in Education

This paper studies the effects of distortionary taxes and public investment in an endogenous growth OLG model with knowledge transmission. Fiscal policy affects growth in two respects: First, work time reacts to variations of prospective tax rates and modifies knowledge formation; second, public spending enhances labour efficiency but also stimulates physical capital through increased savings. It is shown that Ramsey-optimal policies reduce savings due to high tax rates on young generations, and are not necessarily growth-improving with respect to a pure private system. Non-Ramsey policies that shift the burden on adults are always growth-improving due to crowding-in effects: the welfare of all generations is unambiguously higher with respect to a private system, and there generally exists a continuum of non-optimal tax rates under which long-run growth and welfare are higher than with the Ramsey-optimal policy.Endogenous growth, Human capital, Overlapping generations, Tax policy, Public investment.

Identifying a Forward-Looking Monetary Policy in an Open Economy

I identify a forward-looking monetary policy function in a structural VAR model by using forecasts of macroeconomic variables, in addition to the realized variables used in a standard VAR. Both impulse responses and variance decompositions of the monetary policy variable of this forecast-augmented VAR model suggest that forecasted variables play a greater role than realized variables in a central bank’s policy decisions. I also find that a contractionary policy shock instantaneously increases the market interest rate as well as the forecast of the market interest rate. The policy shock also appreciates both the British pound and the forecast of the pound on impact. On the other hand, the policy shock lowers expected inflation immediately, but affects realized inflation with a lag. When I estimate the standard VAR model encompassed in the forecast-augmented model, I find that a contractionary policy shock raises the inflation rate and leads to a gradual appreciation of the domestic currency. However, the inclusion of inflation expectations reverses this puzzling response of the inflation rate, and the inclusion of both the market interest rate forecast and the exchange rate forecast removes the delayed overshooting response of the exchange rate. These findings suggest that a standard VAR may incorrectly identify the monetary policy function.
