Integer programming on domains containing inseparable ordered pairs

Using the integer programming approach introduced by Sethuraman et al. (2003), we extend the analysis of the preference domains containing an inseparable ordered pair, initiated by Kalai and Ritz (1978). We show that these domains admit not only Arrovian social welfare functions “without ties,” but also Arrovian social welfare functions “with ties,” since they satisfy the strictly decomposability condition introduced by Busetto et al. (2015). Moreover, we go further in the comparison between Kalai and Ritz (1978)’s inseparability and Arrow (1963)’s single-peak restrictions, showing that the former condition is more “respectable,” in the sense of Muller and Satterthwaite (1985).     

Executive Gender Pay Gaps: The Roles of Female Risk Aversion and Board Representation

Using a large sample of executives in S&P 1500 firms over 1996–2010, we document significant salary and total compensation gaps between female and male executives and explore two possible explanations for the gaps. We find support for greater female risk aversion as one contributing factor. Female executives hold significantly lower equity incentives and demand larger salary premiums for bearing a given level of compensation risk. These results suggest that females’ risk aversion contributes to the observed lower pay levels through its effect on ex ante compensation structures. We also find evidence that the lack of gender diversity on corporate boards affects the size of the gaps. In firms with a higher proportion of female directors on the board, the gaps in salary and total pay levels are lower. Together, these findings suggest that female higher risk aversion may act as a barrier to full pay convergence, despite the mitigating effect from greater gender diversity on the board.     

Remittances to Latin America from migrants in the United States: Assessing the impact of amnesty programs

The magnitude of remittance flows to Latin America exceeds the combined inflows of foreign direct investment and official development assistance to the region. Since the United States is the destination country of the vast majority of migrants from Mexico, as well as from other Latin American countries, U.S. immigration policy can have a significant impact on the volume of remittances to the Latin American region. This paper studies how a generalized amnesty — a provision in the 1986 Immigration Reform and Control Act (IRCA) — affected immigrants' remitting patterns. In models that control for immigrants' length of residence in the United States and for economic conditions in both the U.S. state of residence and the country of origin, we estimate substantial post-legalization drops in remittances sent home by Mexican-born migrants who legalized through IRCA. Given the potential positive impact of remittances on investment levels, entrepreneurship rates and the development of the financial sector, this finding underscores the importance of gaining a better understanding of the impact that immigration policies in immigrant-receiving countries may have on the stream of remittance flows to immigrant-sending communities in developing regions.     

Asymmetry in mobile access charges: is it an effective regulatory measure?

This paper analyses the regulation of the market of voice call termination on mobile networks, by considering the remedy of asymmetric access charges and the hypothesis of discriminatory retail pricing. In the two way interconnection, the operators revenue depends on two factors: the retail price and the access charge. If the retail prices are different between calls that terminate on the same network (on-net) and calls that terminate on the rival network (off-net), the competition is more complex, involving positive networks externalities for the incumbent operator. In order to reduce the competitive disadvantage for new entrants and smaller operators many European regulation authorities have introduced the remedy of asymmetric access charges. This paper is aimed at analysing the effectiveness of this regulatory measure, assuming that operators are differentiated in terms of brand loyalty and cost structure.     

SME financing and the choice of lending technology in Italy: Complementarity or substitutability?

This paper investigates SME financing in Italy. The literature distinguishes between two main different lending technologies (LTs) for SMEs: transactional and relationship LTs. We find that banks lend to SMEs by using both LTs together, independently of the size and proximity of borrowers. Moreover, we show that the use of soft information decreases the probability of firms being credit rationed. Finally, we find that more soft information is produced when the bank uses relationship LT as primary technology individually or coupled with transactional LT. Our results support the view that LTs can be complementary, but reject the hypothesis that substitutability among LTs is somehow possible for outsiders by means of hardening of soft information.     

Does family planning help the employment of women? The case of India

This paper gives some insight into the existence of a positive effect of family planning programmes on women's employment in developing countries. We study married women aged 15–49 living throughout India using a sample drawn from the National Health Family Survey (NFHS-2) for 1998–1999. We focus on a programme of doorstep services delivered by health or family planning (FP) workers who are sent to visit women in their assigned areas. Results derived from the estimation of fixed effect linear probability and conditional logit models show a positive and significant correlation of the share of women living in a local area (village, town or city) that has been visited by FP workers with the probability of women's employment. A multinomial analysis also shows that the largest positive effect of FP in rural India is to be found on paid work, as opposed to unpaid work, suggesting a potential empowering feedback of demographic measures through labour earnings.     

Representing markets: The shaping of fashion trends by French and Italian fabric companies

In this paper, we use ethnographic methods to describe the market making activities of Première Vision, Paris, the leading trade fair in the clothing fabric industry. Through collective action and powerful representational practices, Première Vision's exhibitors affirm their style innovation and position themselves as trend setters. Our study extends the emerging literature on market forms and marketing practices by (i) introducing a different lens, based on the ideas of postmodern theorists, through which the nature of representation in industrial markets may be viewed and (ii) addressing the role of self-interested theorists, i.e. marketers who theorize about the market and its functioning in ways that are self-beneficial. Our paper also has implications for trade fair literature, which is mostly concerned with individual exhibitors' value appropriation strategies. The case of Première Vision shows that trade fairs may be considered as collective marketing instruments, thus highlighting the importance of organizers' value creation strategies.     

Defending Gibrat’s Law as a long-run regularity

According to Gibrat’s Law of Proportionate Effect, the growth rate of a given firm is independent of its size at the beginning of the period examined. While earlier studies tended to confirm the Law, more recent research generally rejects it. This article reconciles these two streams of literature, taking into account the role of market selection and learning in reshaping a given population of firms through time. Consistently with previous studies, we find that Gibrat’s Law has to be rejected ex ante, since smaller firms tend to grow faster than their larger counterparts. However, a significant convergence toward Gibrat-like behavior can be detected ex post. This finding is an indication that market selection “cleans” the original population of firms, so that the resulting industrial “core” does not depart from a Gibrat-like pattern of growth. From a theoretical point of view, this result is consistent with those models based on passive and active learning, and can be seen as a defense of the validity of the Law in the long-run.

Is lack of funds the main obstacle to growth? ebrd's experience with small- and medium-sized businesses in central and eastern europe

Small- and medium-sized enterprises (SMEs) potentially constitute the most dynamic firms in an emerging economy. They are the ones most likely to move into areas of comparative advantage and high value added, though they often face economic, institutional, and legal obstacles. Obstacles include limited access to working capital and long-term credit, legal and regulatory restrictions, inadequate infrastructure, high transaction costs, and limited managerial and technical expertise. Despite the presence of multiple and often interrelated constraints, however, the widespread belief, on which policies to support SMEs are based, is that the lack of finance constitutes the main obstacle to the growth of SMEs.Enterprise survey work is the tool generally used to deepen our understanding of constraints affecting SMEs formation and growth. The European Bank for Reconstruction and Development (EBRD) is no exception in this respect: during its early years it drew substantially on a set of enterprise surveys conducted by the World Bank between 1991 and 1993 in Hungary, the Czech and Slovak Federal Republic (CSFR), Poland, and Russia investigating the obstacles faced by SMEs. As the volume and geographical spread of its operations increased, the EBRD felt the need to design and run its own surveys, effectively addressing specific issues encountered in the context of its increasing lending and investment activity in central and eastern Europe (CEE). The findings of this analysis confirmed the belief that credit constraints constitute one of the main obstacles to growth of SMEs and encouraged the EBRD to tailor its financing instruments to the stage of transition of the country in question and the ability of the local financial system to assume key responsibilities.This paper analyzes the way in which the EBRD strives to correct this capital market failure in the region in which it operates. The fundamental principles on which EBRD policy is based are: a preference for reaching the SMEs via local financial intermediaries, a commercial approach to the provision of finance, and finally a focus on development of the local financial system as a whole. It is still too early to draw conclusions on EBRD activity in the field of SMEs financing based on other types of indicators than data on volume of signed commitments. A large part of the loans is still in the grace period, therefore investments are in an early phase and operation performance evaluation reports on this type of operations are still too few. Aggregate data on volume of EBRD financing through financial intermediaries paint an encouraging picture. A 250% increase in the volume of such operations between 1994 and 1997, a nine-fold increase in the number of subprojects between 1995 and 1997, and an ever-widening geographical spread of activities and decreasing size of subprojects indicate that the experience of the EBRD in financing through financial intermediaries is on the whole positive. Financing provided to intermediaries is not necessarily always intended, nor guaranteed to reach SMEs. It is, however, guaranteed to create the appropriate financing channels which are necessary to ease the SMEs' liquidity constraint.This paper discusses the shortcomings of the financial system in the CEE countries. It outlines the EBRD policy to support SMEs and the various instruments employed so far and presents selected case studies to throw light on how good project design can help overcome difficult environments and lower the perception of risk connected to indigenous SMEs. A summary of the findings of the survey work conducted by the EBRD in the region is also presented.
