| This paper argues that mainstream economics does not follow the positivist research tradition it (often implicitly) claims to follow and expresses some serious doubt that econometrics in particular can make economics a hard science. Mathematical rigour and sophisticated statistical techniques may be regarded as persuasive analytical tools in economics, but their mere application does not guarantee good research practice. The paper outlines an alternative methodological view of pragmatic instrumentalism in which the well known tools of economic analysis can find a new place. Instead of relying on a narrow rule that purports to produce universal truth, this view encourages to increase the target area for questioning and probing. Much more attention is paid... |

| This report provides information on the impact of CIMMYT training, based on a set of background interviews with center staff, reviews of relevant data and documents provided by CIMMYT, and two surveys: one of research leaders in trainees’ countries of origin and one of participants in CIMMYT courses on maize and wheat improvement, quality protein maize, soil-borne pathogens of cereals, and maize stress breeding during 2002-04. Evidence indicates that training provided by CIMMYT not only furnishes new knowledge and skills, but results in new ways of thinking about research and new research partnerships, is often shared within trainees’ home institutions, and changes the way the institutions work. The evidence in this study establishes the existence of... |

| This paper builds a general test of contagion in financial markets based on bivariate correlation analysis a test that can be interpreted as an extension of the normal correlation theorem. Contagion is defined as a structural break in the data generating process of rates of return. Using a factor model of returns as theoretical framework, we nest leading contributions in the literature as special cases of our test. We show that, while the literature on correlation analysis of contagion is successful in controlling for a potential bias induced by changes in the variance of global shocks, current tests are conditional on a specific yet arbitrary assumption about the variance of country specific shocks. Our results suggest that, for a number of pairs of... |

| This paper investigates the law of motion for the cross-section distribution of dietary energy supply (DES) in the world. This has been pursued using the distribution approach and a panel of 152 countries for the period 1961-2001. According to the empirical results, persistence in caloric intakes dominates in the short-run. With time, however, upwards mobility gains momentum and the world is moving towards a long-run distribution, which is strongly skewed to the left. The estimated expected first passage times from extreme under-supply to higher intake levels are consistent with speculations that most of the developing countries will attain the 3000 kcal per person per day level by the year 2030. |

| The paper is inviting a reader to think to what extent we can use the knowledge resulting from laws of nature for exploring economic processes. In order to look for the answers on this question, the paper is going to explore international trade flows between the Baltic Sea region countries using a gravity approach. Attention is paid to analyzing forces that attract foreign trade flows and to exploring the influence of distance as an indicator that expresses both transportation costs and cultural proximity of the countries. The results of modeling support the statement that the size of economy has statistically significant and positive influence on the bilateral trade relations of the region. The influence of economic development level that is expressed by... |

| The aim of this article is to explore, through a hedonic approach, the factors that might explain the price variability for the French-managed fishery of scallop at primary fish markets. In addition to factors classically identified in the current literature like intrinsic product characteristics or markets situation, the characteristics of operators are tested. The relationships of loyalty between sellers and buyers, and market assiduity are notably considered. |

| In developing countries such as Malaysia, the availability of reinsurance arrangements provides several advantages to the primary insurers such as keeping their risk exposures at prudent levels by having their large risk exposures reinsured by another company, meeting client requests for larger insurance coverage by having their limited financial sources supported by another company, and acquiring underwriting skills, experience and ability of handling complex claims by depending on another company for such services. This paper aims to model insurance claims and assess the insolvency probability of reinsurance treaties. Claims data was obtained from one of the leading insurers in Malaysia and R programming with actuar package is used to compute the... |

| Over the time a large number of reciprocal preferential trade agreements (RTAs) have been concluded among countries. Recently many studies have used gravity equations in order to estimate the effect of RTAs on trade flows between partners. These studies report very different estimates since they differ greatly in data sets, sample sizes and independent variables used in the analysis. So, what is the "true" impact of RTAs? This paper combines, explains and summarizes a large number of results (1827 estimates included in 85 papers), using a meta-analysis (MA) approach. Notwithstanding quite a high variability, studies consistently find a positive RTAs impact on bilateral trade: the hypothesis that there is no effect of trade agreements on trade is easily and... |

| In 1881, Newcomb conjectured that the first significant digits (FSDs) of numbers in statistical tables would follow a logarithmic distribution with the digit “1” occurring most often. However, because Newcomb’s proposal was not presented with a theoretical basis, it was not given much attention. Fifty-seven years later, Benford argued for the same principle and showed it was relevant to a large range of data sets, and the logarithmic FSD distribution became known as “Benford’s Law.” In the mid-1940s, Stigler claimed Benford’s Law contained a theoretical inconsistency and supplied an alternative derivation for the distribution of FSDs. In this paper, we examine the theoretical basis of the Stigler distribution and extend his reasoning by incorporating FSD... |
