Second‐order analysis of anisotropic spatiotemporal point process data

Second‐order orientation methods provide a natural tool for the analysis of spatial point process data. In this paper, we extend to the spatiotemporal setting the spatial point pair orientation distribution function. The new space–time orientation distribution function is used to detect space–time anisotropic configurations. An edge‐corrected estimator is defined and illustrated through a simulation study. We apply the resulting estimator to data on the spatiotemporal distribution of fire ignition events caused by humans in a square area of 30 × 30 km² for 4 years. Our results confirm that our approach is able to detect directional components at distinct spatiotemporal scales. © 2014 The Authors. Statistica Neerlandica © 2014 VVS.     

IDENTIFYING THE EFFECTS OF SIMULTANEOUS MONETARY POLICY SHOCKS

Many central banks, particularly in the developing world, aim for exchange rate stability as a macroeconomic goal. However, most are reluctant to relinquish monetary policy autonomy, so they end up operating through both interest rate and foreign exchange interventions. But the use of multiple policy instruments does not necessarily equip monetary authorities with better tools to achieve their targets. On the contrary, their effects can potentially offset each other. Using daily data from the Central Bank of Colombia during the period of 1999–2012, I study the effects of simultaneous policies by first deriving new measures of monetary shocks and then determining their impact on economic activity. The main findings indicate that (a) while interest rate interventions have a significant impact on real and nominal variables, foreign exchange interventions tend to have limited effects; and (b) empirical anomalies, such as the positive relationship between output growth, inflation, and the policy rate are eliminated when properly accounting for the systematic responses of policy.

Does Legal Tradition Affect Competition Policy Performance?

During the early 1990's, in the early days of the worldwide competition policy boom, Spencer Waller and Joshua Newberg argued that difficulties inherent in grafting common law concepts—such as antitrust—onto non common law traditions would undermine the administration of competition law in non common law tradition countries. Recent independent survey data on the performance of competition programs in 102 nations shows deplorable differences in performance, lending some weight to the Waller-Newberg thesis.

This article tests whether differences in legal tradition contributes to the observed variance in competition agency performance.

A careful understanding of the influence of legal tradition and other factors underscoring the relevance, shortcomings and problems of competition policy performance are useful for determining whether competition programs should be at all reproduced elsewhere, whether they should be modified prior to adoption or whether they should be adopted verbatim. Familiarity with performance factors is also useful both for program administration and program sequencing. Comparative examinations of competition programs enable decision-makers to properly allocate resources and to address policy issues.

The estimated model is a two-stage least-squares cross-section analysis between competition policy performance and various control variables, including the presence of a common law tradition. Limitations on the availability of control and instrumental variables, reduces the data set from 102 to 82 nations.

Succinctly, after accounting for other explanatory variables such as gross domestic product per capita, foreign direct investment, imports, physical size, the level of corruption, and national experience with a modern antitrust law, one can attribute statistical significance to historical legal tradition as established by the Waller-Newberg hypothesis.     

Peasant differentiation and service provision in Colombia

This paper contributes to agrarian debates through a discussion of the interactions between the interests and incentives of the rural classes, focusing especially on the leadership exercised by middle‐size farmers. In the recent past, class analysis associated with Marxism has given way to models of individual rational maximization, not least because of the lack of specific findings about the effects of peasant differentiation beyond the dichotomous class conflict between peasants and landlords. Information has replaced asset distribution as the main factor affecting effective governance and service provision. According to these theories, politicians did not deliver less because they were responding to the preferences of the large landowning classes, or because seemingly competitive elections were games of rotating chairs within a single dominant class but, rather, because the voters did not have enough information about the candidates and programmes. I bring the discussion back to peasant differentiation and class endowments using the case of communal action boards in Colombia, showing how the demand for information on candidates and developmental resources matters, but is dependent on class structures. I suggest that different rural groups access, use, and manipulate information with differing aims, and that the rural middle class is a fundamental actor in the demand for public goods.     

Duplication without constraints: Álvarez‐Nogal and Chamley's analysis of debt policy under Philip II

Carlos Álvarez‐Nogal and Christophe Chamley recently published an article in the Economic History Review on ‘Debt policy under constraints: Philip II, the Cortes, and Genoese bankers’. In this note, we show that several claims in their article are very similar to earlier research results, published or circulated long before Álvarez‐Nogal and Chamley's original submission, by ourselves and other scholars (section I). These results are repeated without attribution or even mention of the earlier work. In addition, we show that what Álvarez‐Nogal and Chamley present as new quantitative insights are actually replications of earlier results of ours (section II). Finally, Álvarez‐Nogal and Chamley misrepresent our contributions, as well as those of several other scholars (section III).     

Which Creditors’ Rights Drive Financial Deepening and Economic Development?

Since the 1990s financial economists have documented the essential role of creditors' rights in encouraging lenders to provide credit. This article demonstrates the central importance of creditors' ability to use movable assets such as inventories and accounts receivable (as distinct from immovable assets like real estate) as collateral when lending to business enterpriseses. Using a unique cross‐country, micro‐level loan data set that contains loan‐to‐value ratios for different assets, the authors found that the loan‐to‐values of loans that are collateralized with movable assets were lower in countries with weak collateral laws for movable assets, and that lending in such countries was biased toward the use of immovable assets. Using sector‐level data, the authors also found that weak movable collateral laws were associated with distortions in the allocation of resources that favored immovable‐based production and investment. The effects of resources that favored immovable‐based production and investment. The effects of the collateral law reform enacted in Slovakia in 2003 were held up as providing support for the authors' findings. The authors also investigated which aspects of movable assets collateralization regimes are most important for facilitating the use of movable assets as collateral. They concluded that the two critical features of such regimes are the registration of collateral interests—which facilitates monitoring of collateral and avoids double pledging—and the ability of creditors to avoid lengthy court proceedings when taking possession of collateral. These findings suggest that it would be relatively easy for many countries to increase their supply of credit because reforming these aspects of legal regimes is fairly straightforward with few political obstacles.     

Why Do Resource-Abundant Economies Grow More Slowly?

This article suggests an alternative explanation for why resource-rich economies have lower growth rates: because they are likely to be living beyond their means. It is shown that overshooting the steady state's equilibrium consumption and investment can be optimal in a Ramsey growth model with natural resources. Therefore, the economy will converge to its steady state from above, displaying negative growth rates on the transition. A dynamic general equilibrium model is calibrated to the Venezuelan economy and shown to approximate the economy's performance over the oil boom years adequately.     

Residential Land Values and the Decentralization of Jobs

The land-value surface in suburban Washington, D.C., changed dramatically over the decade of the 1980s. This article explains these changes in terms of the decentralization of jobs versus socioeconomic trends. Contemporaneous correlation among selected variables needs to be controlled with reduced forms and SES techniques. But all explanatory variables except distance from some unchanged point are determined simultaneously. Predetermined variables control for this double-endogeneity issue.Land values in 1990 have a U-shape with respect to distance from the U.S. Capitol Building after controlling for other variables. The data indicate that this is the result of demographic changes rather than the development of suburban employment nodes: polycentric SUE theory is rejected. Land values are an increasing function of lagged land values, a decreasing function of work at home. Moreover, work at home is attracted by low structural density and high socioeconomic status as well as low land values. This supports the argument that demographics and technological innovations have shaped the land-value surface; baby boomers are seeking low-density housing for work and family life.     

Recruitment advertising: The marketing-human resource interface

The common perception of recruitment advertising is of the "want ads" in the local or national newspapers. Despite the lack of academic interest, in some cases, recruitment advertising has adopted the color, imagination, and creativity of consumer advertising. Some recruiters have recognized the marketing benefits of job ads and the need for a corporate communications policy covering all company communications. This paper examines the limited literature on recruitment advertising. The authors compile a list of characteristics of marketing-oriented recruitment advertisements and apply these to their exploratory analysis of the recruitment section of one popular Sunday newspaper in the United Kingdom.     

Key success factors for strategy implementation in Latin America

Increasing competition among Latin American firms fosters more proactive processes aimed at reviewing business strategy. The research objective is to measure the impact of key variables on successful implementation of business strategy. Relying on the knowledge and experience of Latin American entrepreneurs and managers, the questions addressed include: How important is the role of the CEO and management actors? Do firms prioritize actions prior to implementing strategy? Are control and follow-up tools valued? How is a successful strategy implementation ensured? Research findings are expected to provide useful knowledge for management decision processes relating to successful implementation of business strategy.
