International Entrepreneurship in Bottom of the Pyramid Markets – Overcoming institutional constraints

Bottom of the pyramid (BoP) markets are an underserved market of approximately four billion people living on under $5 a day in four regional areas: Africa, Asia, Eastern Europe and Latin America. According to estimations, the BoP market forms a $5 trillion global consumer market. Despite the potential of BoP markets, companies have traditionally focused on serving the markets of developed countries and ignored the large customer group at the bottom of the pyramid. The BoP approach as first developed by Prahalad and Hart in 2002 has focused on multinational corporations (MNCs), which were thought of as the ones who should take responsibility in serving the customers at the bottom of the pyramid. This study challenges this proposition and gives evidence that also smaller international new ventures – entrepreneurial firms that are international from their birth, can be successful in BoP markets. BoP markets are characterized by a number of deficiencies in the institutional environment such as strong reliance on informal sector, lack of infrastructure and lack of skilled labor. The purpose of this study is to increase the understanding of international entrepreneurship in BoP markets by analyzing how international new ventures overcome institutional constraints in BoP markets and how institutional uncertainty can be exploited by solving institutional problems. The main objective is divided into four sub objectives. • To describe the opportunities and challenges BoP markets present • To analyze the internationalization of INVs to BoP markets • To examine what kinds of strategies international entrepreneurs use to overcome institutional constraints • To explore the opportunities institutional uncertainty offers for INVs Qualitative approach was used to conduct this study and multiple-case study was chosen as a research strategy in order to allow cross-case analysis. The empirical data was collected through four interviews with the companies Fuzu, Mifuko, Palmroth Consulting and Sibesonke. The results indicated that understanding of the wider institutional environment improves the survival prospects of INVs in BoP markets and that it is indeed possible to exploit institutional uncertainty by solving institutional problems. The main findings were that first-hand experience of the markets and grassroots levels of information are the best assets in internationalization to BoP markets. This study highlights that international entrepreneurs with limited resources can improve the lives of people at the BoP with their business operations and act as small-scale institutional entrepreneurs contributing to the development of the institutional environment of BoP markets.

Wrap around analysis of the affordances and constraints for girls with physical disabilities participating in physical activities /

This is a qualitative study exploring the physical activity patterns of a group of women with physical disabilities through their lifespan. In-depth interviews were done with a group of 6 women aged 1 9 to 3 1 . The data were analyzed via content and demographic strategies. Participants in this study reported that their physical activity patterns and their experiences related to their physical activity participation changed over their lives. They were most physically active in their youth (under 14 years of age) and as they reached high school age (over 14 years of age) and to the present time, they have become less physically active. They also reported both affordances and constraints to their physical activity participation through their lifespan. In their youth, they reported affordances such as their parents' assistance, an abundance of available physical activity opportunities, and independent unassisted mobility, as all playing an important factor in their increased youth physical activity. In adulthood, the participants' reported less time, fewer opportunities for physical activity, and reliance on power mobility as significant constraints to their physical activity. The participants reported fewer constraints to being physically active in their youth when compared to adulthood. Their reasons for participation in physical activity changed from fun and socialization in their youth instead of for maintenance of health, weight, and function in adulthood. These affordances, constraints and reasons for physical activity participation were supported in the literature.

Bounds on edit metric codes with combinatorial DNA constraints

The design of a large and reliable DNA codeword library is a key problem in DNA based computing. DNA codes, namely sets of fixed length edit metric codewords over the alphabet {A, C, G, T}, satisfy certain combinatorial constraints with respect to biological and chemical restrictions of DNA strands. The primary constraints that we consider are the reverse--complement constraint and the fixed GC--content constraint, as well as the basic edit distance constraint between codewords. We focus on exploring the theory underlying DNA codes and discuss several approaches to searching for optimal DNA codes. We use Conway's lexicode algorithm and an exhaustive search algorithm to produce provably optimal DNA codes for codes with small parameter values. And a genetic algorithm is proposed to search for some sub--optimal DNA codes with relatively large parameter values, where we can consider their sizes as reasonable lower bounds of DNA codes. Furthermore, we provide tables of bounds on sizes of DNA codes with length from 1 to 9 and minimum distance from 1 to 9.

The Informational Value of Corporate Credit Ratings

This thesis examines the quality of credit ratings issued by the three major credit rating agencies - Moody’s, Standard and Poor’s and Fitch. If credit ratings are informative, then prices of underlying credit instruments such as fixed-income securities and credit default insurance should change to reflect the new credit risk information. Using data on 246 different major fixed income securities issuers and spanning January 2000 to December 2011, we find that credit default swaps (CDS) spreads do not react to changes in credit ratings. Hence credit ratings for all three agencies are not price informative. CDS prices are mostly determined by historical CDS prices while ratings are mostly determined by historical ratings. We find that credit ratings are marginally more sensitive to CDS than CDS are sensitive to ratings.

Effects of credit rating change on risk-taking

This thesis investigates whether there are changes in risk-taking behavior following an upgrade or downgrade in credit ratings. Research on effects of rating changes on capital markets is well-documented but the literature on how rating changes may affect firm behavior is sparse. Following, a downgrade in credit rating, managers may increase risk-taking to improve their overall performance or reduce risk-taking following upgrades to ensure that their performance is assessed more on the basis of what they may deem success in the form of an upgrade. Using a sample of firms trading in the U.S from 1994-2013, we find evidence of change in risk-taking behavior. We use cross-sectional regressions and matching using propensity scores and Barber and Lyon (1997) methodology to measure changes in risk-taking and we do find evidence of changes in managerial risk-taking behavior. Furthermore, we find that the direction of change (increase or decrease) in some cases is dependent on the type of measure rather than the type of rating change.

On the Profitability of Production Constraints in a Dynamic Natural Resource Oligopoly

Static oligopoly analysis predicts that if a single firm in Cournot equilibrium were to be constrained to contract its production marginally, its profits would fall. on the other hand, if all the firms were simultaneously constrained to reduce their productino, thus moving the industry towards monopoly output, each firm's profit would rise. We show that these very intuitive results may not hold in a dynamic oligopoly.

Essays in open economy macroeconomics with borrowing frictions

Cette thèse comporte trois essais en macroéconomie en économie ouverte et commerce international. Je considère tour à tour les questions suivantes: sous quelles conditions est-il optimal pour un pays de former une union économique? (essai 1); l'augmentation de la dispersion transversale des avoirs extérieurs nets des pays est-elle compatible avec une dispersion relativement stable des taux d'investissement? (essai 2); le risque de perte de marché à l'exportation du fait de l'existence des zones de commerce préférentiel joue t-il un rôle dans la décision des pays exclus de négocier des accords commerciaux à leur tour? (essai 3). Le premier essai examine les conditions d'optimalité d'une union économique. Il s'intéresse à une motivation particulière: le partage du risque lié aux fluctuations du revenu. Dans la situation initiale, les pays ont très peu d'opportunités pour partager le risque à cause des frictions: les marchés financiers internationaux sont incomplets et il n'y pas de mécanisme pour faire respecter les contrats de crédit entre pays. Dans ce contexte, une union économique apparait comme un arrangement qui pallie à ces frictions entre les pays membres seulement. Cependant, l'union dans son ensemble continue de faire face à ces frictions lorsqu'elle échange avec le reste du monde. L'arbitrage clé dans le modèle est le suivant. D'un coté, l'intégration économique permet un meilleur partage du risque entre pays membres et la possibilité pour le partenaire pauvre d'utiliser la ligne de crédit du partenaire riche en cas de besoin. De l'autre coté, l'union peut faire face à une limite de crédit plus restrictive parce que résilier la dette extérieure est moins coûteux pour les membres l'union. De plus, le fait que le partenaire pauvre peut utiliser la limite de crédit du partenaire riche génère une externalité négative pour ce dernier qui se retrouve plus fréquemment contraint au niveau des marchés internationaux des capitaux. En conformité avec les faits observés sur l'intégration économique, le modèle prédit que les unions économiques sont relativement peu fréquentes, sont plus susceptibles d'être créées parmi des pays homogènes, et généralement riches. Le deuxième essai porte sur la dispersion des avoirs extérieurs nets et la relation avec la dispersion des taux d'investissement. Au cours des récentes décennies, la dispersion croissante des déséquilibres extérieurs et les niveaux record atteints par certaines grandes économies ont reçu une attention considérable. On pourrait attribuer ce phénomène à une réduction des barrières aux mouvements internationaux des capitaux. Mais dans ce cas, il est légitime de s'attendre à une augmentation de la dispersion au niveau des taux d'investissement; ceci, parce que le financement des besoins en investissements constitue une raison fondamentale pour laquelle les pays échangent les capitaux. Les données indiquent cependant que la dispersion des taux d'investissement est restée relativement stable au cours des récentes décennies. Pour réconcilier ces faits, je construis un modèle d'équilibre général dynamique et stochastique où les pays sont hétérogènes en raison des chocs idiosyncratiques à leurs niveaux de productivité totale des facteurs. Au niveau des marchés internationaux des capitaux, le menu des actifs disponibles est restreint à une obligation sans risque et il n'y a pas de mécanisme pour faire respecter les contrats de crédit entre pays. A tout moment, un pays peut choisir de résilier sa dette extérieure sous peine d'exclusion financière et d'un coût direct. Ce coût direct reflète les canaux autres que l'exclusion financière à travers lesquels les pays en défaut sont pénalisés. Lorsque le modèle est calibré pour reproduire l'évolution de la dispersion transversale des avoirs extérieurs nets, il produit une dispersion relativement stable des taux d'investissement. La raison principale est que les incitations que les pays ont à investir sont liées à la productivité. Avec l'intégration financière, même si les opportunités d'emprunt se sont multipliées, les incitations à investir n'ont pas beaucoup changé. Ce qui permet de générer une dispersion accrue de la position des avoirs extérieurs nets des pays avec une dispersion relativement stable des taux d'investissement. Le troisième essai analyse un aspect de l'interdépendance dans la formation des accords commerciaux préférentiels: j'examine empiriquement si le risque de diversion des exportations en faveur des pays membres des zones de commerce préférentiel est un facteur déterminant dans la décision des pays exclus de ces accords de négocier un accord à leur tour. Je construis un indicateur qui mesure le potentiel de diversion des exportations auquel font face les pays et estime un modèle probit de formation des zones de commerce préférentiel créées entre 1961 et 2005. Les résultats confirment que les pays confrontés à un plus grand potentiel de détournement des échanges sont plus susceptibles de former une zone de commerce préférentiel à leur tour.
