Accounting for Spatial Effects in Economic Models of Land Use: Recent Developments and Challenges Ahead

The marked increase in the availability of spatial data has forced researchers engaged in land use modeling to directly confront the question of space and the theoretical and methodological challenges involved in developing spatial models. Advances have come from multiple disciplines, most notably through the development and application of spatial theory and methods from regional science, geography, urban economics and more recently, theoretical and applied econometrics. The main goal of this paper is to summarize the econometric challenges of spatial data and to highlight spatial models and methods with a particular focus on models of land markets and land use change. We also discuss the data and modeling challenges associated with modeling the underlying spatial economic mechanisms that give rise to land use patterns and the complexities involved in modeling land use as a coupled economic-ecological system.     

Estimating the intergenerational persistence of lifetime earnings with life course matching: Evidence from the PSID

Why do estimates of the intergenerational persistence in earnings vary so much for the United States? Recent research suggests that lifecycle bias may be a major factor [Grawe, N., Lifecycle bias in estimates of intergenerational earnings persistence. Labour Economics 2006, 13:551–570; Haider, S., and Solon, G., Life-cycle variation in the association between current and lifetime earnings. American Economic Review 2006, 96(4):1308–1320.]. In this paper we estimate the intergenerational correlation in lifetime earnings by using sons' and fathers' earnings at similar ages in order to account for lifecycle bias. Our estimate based on earnings measured at 35–44 for both fathers and sons is similar to that for the age range 45–54.     

Regret in auctions: theory and evidence

The sealed-bid first-price auction of a single object in the case of independent privately-known values is the simplest auction setting and understanding it is important for understanding more complex mechanisms. But bidders bid above the risk-neutral Nash equilibrium theory prediction. The reasons for this “over bidding” remain an unsolved puzzle. Several explanations have been offered, including risk aversion, social comparisons, and learning. We present a new explanation based on regret and a model that explains not only the observed over bidding in sealed-bid first-price auctions, but also behavior in several other settings that is inconsistent with risk aversion.

Who Has the Time? Community College Students’ Time-Use Response to Financial Incentives

We evaluate the effect of performance-based scholarship programs for post-secondary students on student time use and effort and whether these effects are different for students we hypothesize may be more or less responsive to incentives. To do so, we administered a time-use survey as part of a randomized experiment in which community college students in New York City were randomly assigned to be eligible for a performance-based scholarship or to a control group that was only eligible for the standard financial aid. This paper contributes to the literature by attempting to get inside the “black box” of how students respond to a monetary incentive to improve their educational attainment. We find that students eligible for a scholarship devoted more time to educational activities, increased the quality of effort toward and engagement with their studies, and allocated less time to leisure. Additional analyses suggest that students who were plausibly more myopic (place less weight on future benefits) were more responsive to the incentives, but we find no evidence that students who are arguably more time constrained were less responsive to the incentives.

     

Social-economic Development of Small West European Peripheral Countries

In the framework of different countries＇ international comparison, the objective of this paper reflects research topic of investigation--the identification of small countries, revealing features of economic development and business growth in economic history context of small economies classification. The object of investigation focuses on West European and Nordic countries＇ small economies. The hypothesis of the article is that small states under consideration are developing as the business competitive peripheries areas due to the special Scandinavian capitalist model development characterized by high level of social capital. The statistical data base includes Organization of Economic Cooperation and Development indicators, World Bank parameters and Nordic transnational corporation＇s annual reports. The paper considers the following research questions： （1） the critical overview of the mainstream academicians opinions concerning different-scaled economies, （2） classification of small states and clarification of different groups of the small-scaled countries role in the world and regional economy through historical context, （3） estimates and variants of small countries＇ social-economic development in accordance with different parameters, （4） consideration of Nordic European countries coming to the business model of the competitive peripheral social-economic development. The main summing up conclusion is that small economies of Nordic Europe are converting nowadays into the experimental laboratory of the European and world economy due to the specific model of their social-oriented economic and business growth, their geopolitical location between developed European integration complex embracing presumably small-scaled states from one side and large-scaled emerging market economy of Asian continent from the other side.     

Euro vs Dollar: An Improbable Threat

Ever since the setting up of the EMU, many scholars have argued that the Euro will take its place alongside the dollar and perhaps even replace it as international money. The theory behind this point of view is represented by search-theoretic models. The fundamental shortcoming of the traditional version of these models is that they fail to make a distinction between different types of money, in particular between commodity money and fiduciary money. In the international context a fiduciary money can be accepted only when a political exchange is possible between a leading country which has an interest in producing trust in the future value of its currency and other countries which attach no importance to the relative gains the issuing country acquires by exploiting the privilege of seigniorage. The Bretton Woods system and the dollar standard, although based on fiduciary monies, have worked thanks to the institutional framework maintained by the United States and accepted by other countries. Unlike the United States, the euro area is not in a position to exercise any form of political leadership on the international scene. As things stand the euro does not represent a threat to the dollar and it is bound to remain a regional money.     

Does Ethnic Discrimination Vary Across Minority Groups? Evidence from a Field Experiment*

We conduct a large‐scale field experiment to measure labour market discrimination in Australia, one quarter of whose population was born overseas. To denote ethnicity, we use distinctively Anglo‐Saxon, Indigenous, Italian, Chinese and Middle Eastern names. We compare multiple ethnic groups, rather than a single minority as in most other studies. In all cases we applied for entry‐level jobs and submitted a CV indicating that the candidate attended high school in Australia. We find significant differences in callback rates: ethnic minority candidates would need to apply for more jobs in order to receive the same number of interviews. These differences vary systematically across ethnic groups.     

A framework to measure integrated risk

A framework underlying various models that measure the credit risk of a portfolio is extended in this paper to allow the integration of credit risk with a range of market risks using Monte Carlo simulation. A structural model is proposed that allows interest rates to be stochastic and provides closed-form expressions for the market value of a firm's equity and its probability of default. This model is embedded within the integrated framework and the general approach illustrated by measuring the risk of a foreign exchange forward when there is a significant probability of default by the counterparty. For this example moving from a market risk calculation to an integrated risk calculation reduces the expected future value of the instrument by an amount that could not be calculated using the common pre-settlement exposure technique for estimating the credit risk of a derivative.     

Land use externalities, open space preservation, and urban sprawl

Parcel data on residential land conversion are used to investigate how land use externalities influence the rate of development and modify policies designed to manage urban growth and preserve open space. Several “smart growth” policies are found to significantly influence land conversion, including a development clustering policy that concentrates development and generates preserved open space. In addition to directly affecting a parcel's hazard rate of conversion, this policy is found to affect neighboring parcels' conversion by generating a positive open space externality that hastens their development. The implication that the clustering policy could generate a more sprawled pattern of development is explored using spatial simulation.
