How does credit access affect children's time allocation? Evidence from rural India

Using a unique dataset obtained from rural Andhra Pradesh, India that contains direct observations of household access to credit and detailed time use, results of this study indicate that credit market failures lead to a substantial reallocation of time used by children for activities such as schooling, household chores, remunerative work, and leisure. The negative effects of credit constraints on schooling amount to a 60% decrease of average schooling time. However, the magnitude of decrease due to credit constraints is about half that of the increase in both domestic and remunerative child labor, the other half appearing to come from a reduction in leisure.

Self-Fulfilling Price Cycles

This paper presents a model of a self-fulfilling price cycle in an asset market. Price oscillates deterministically even though the underlying environment is stationary. The mechanism that we uncover is driven by endogenous variation in the investment horizons of the different market participants, informed and uninformed. On even days, the price is high; on odd days it is low. On even days, informed traders are willing to jettison their good assets, knowing that they can buy them back the next day, when the price is low. The anticipated drop in price more than offsets any potential loss in dividend. Because of these asset sales, the informed build up their cash holdings. Understanding that the market is flooded with good assets, the uninformed traders are willing to pay a high price. But their investment horizon is longer than that of the informed traders: their intention is to hold the assets they purchase, not to resell. On odd days, the price is low because the uninformed recognise that the informed are using their cash holdings to cherry-pick good assets from the market. Now the uninformed, like the informed, are investing short-term. Rather than buy-and-hold as they do with assets purchased on even days, on odd days the uninformed are buying to sell. Notice that, at the root of the model, there lies a credit constraint. Although the informed are flush with cash on odd days, they are not deep pockets. On each cherry that they pick out of the market, they earn a high return: buying cheap, selling dear. However they don't have enough cash to strip the market of cherries and thereby bid the price up.

Restrição ao crédito educacional e investimentos em capital humano no Brasil: evidências através dos retornos à educação

Este artigo procura identificar o papel de restrição ao crédito sobre a decisão de investimento em capital humano no Brasil. Para tanto é usada a hipótese de que custos diretos e de oportunidade de estudar afetam pessoas restritas e não restritas por crédito de forma diferente. Enquanto o custo de oportunidade afeta a todos de forma similar, o custo direto afeta mais fortemente aqueles restritos ao crédito. A partir da estimação de taxas de retorno à educação com o uso de diferentes variáveis instrumentais é possível lançar luz sobre o papel da restrição ao crédito sobre escolaridade. Ao comparar as taxas de retorno utilizando como instrumento a oferta relativa de professores (Proxy dos custos diretos) e salário mediano dos jovens (variável de custo de oportunidade), encontramos uma acentuada diferença no ponto estimado, indicando a existência de efeito da restrição sobre escolaridade. Entretanto, o mau desempenho do segundo instrumento no segundo estágio torna problemática a comparação.

DSGE model with banking sector for emerging economies : estimated using Bayesian methodology for Brazil

Economias emergentes sofrem importantes restrições de crédito quando comparadas com economias desenvolvidas, entretanto, modelos estocásticos de equilíbrio geral (DSGE) desenhados para economias emergentes ainda precisam avançar nessa discussão. Nós propomos um modelo DSGE que pretende representar uma economia emergente com setor bancário baseado em Gerali et al. (2010). Nossa contribuição é considerar uma parcela da renda esperada como colateral para empréstimos das famílias. Nós estimamos o modelo proposto para o Brasil utilizando estimação Bayesiana e encontramos que economias que sofrem restrição de colateral por parte das famílias tendem a sentir o impacto de choques monetários mais rapidamente devido a exposição do setor bancário a mudanças no salário esperado.

Restrição financeira, tangibilidade e capital de giro : como as empresas brasileiras investem

Utilizando dados em Painel sobre mais de 15.000 observações de empresas brasileiras, tanto de capital aberto quanto de capital fechado no período entre 2010 a 2014, o presente estudo examinou a existência de restrição ao crédito e sua relação com investimentos em ativos fixos e o papel desempenhado pelo capital de giro enquanto ferramenta gerencial nas decisões de investimentos em ativos fixos. Para tanto, foram utilizadas duas metodologias-base: o estudo desenvolvido por Almeida e Campello (2007), que inovou ao incluir variáveis que controlam algumas das maiores críticas aos estudos relacionados à restrição ao crédito e o estudo de Ding, Guariglia e Knight (2011) que testou a relação de investimentos em capital de giro com investimentos em ativos fixos. Os resultados encontrados neste trabalho apontam que, de maneira geral, as empresas brasileiras sofrem com restrições ao crédito e também, que as empresas que investem mais em capital de giro demonstram menor sensibilidade do investimento em ativo fixo ao fluxo de caixa, porém, não conseguem traduzir isso em taxas maiores de investimentos.

Impactos do Crédito Rural na produtividade da terra e do trabalho nas regiões brasileiras

O objetivo deste trabalho é mensurar os impactos do crédito rural sobre a produtividade da terra e do trabalho nas grandes regiões brasileiras. A abordagem metodológica é baseada em modelo de restrição de crédito e no método do propensity score. Foram utilizados microdados do Censo Agropecuário de 2006. Os resultados mostram que o crédito não foi efetivo para aumentar a produtividade dos fatores no setor agrícola, exceto para a região nordeste do Brasil. Os resultados apontam para a necessidade de melhorias na política de crédito rural no Brasil.

FDI and Export Participation of Local Firms in Africa: The Case of the Kenyan Garment Industry

FDI in the garment sector has been the single case of large-scale manufacturing investment in African low-income countries since the 1990s. While FDI has triggered the development of local industries in many developing countries, it has not yet been realized in Africa. This paper describes the spillover process in the Kenyan garment industry and investigates the background of local firms' behavior through firm interviews and simulation of expected profits in export market. It shows that credit constraint, rather than absorptive capacity, is a primary source of inactive participation in export opportunity. Only firms which afford additional production facilities without sacrificing stable domestic supply may be motivated to start exporting. However, in comparison with successful Asian exporters, those firms were not as motivated as Asian firms due to the large gap in expected profits.

Liability dollarization and fear of floating

This paper explores the idea that fear of floating can be justified as an optimal discretionary monetary policy in a dollarized emerging economy. Specifically, I consider a small open economy in which intermediate goods importers borrow in foreign currency and face a credit constraint. In this economy, exchange rate depreciation not only worsens importers' net-worth but also increases the financing amount in domestic currency, therefore exaggerating their borrowing finance premium. Besides, because of high exchange rate pass-through into import prices, fluctuations in the exchange rate also have strong impacts on domestic prices and production. These effects, together, magnify the macroeconomic consequences of the floating exchange rate policy in response to external shocks. The paper shows that the floating exchange rate regime is dominated by the fixed exchange rate regime in the role of cushioning shocks and in welfare terms.

Liquidity Constraint and Child Labor In India: Is Market Really Incapable Of Eradicating It From Wage-Labor Households?

One way to measure the lower steady state equilibrium outcome in human capital development is the incidence of child labor in most of the developing countries. With the help of Indian household level data in an overlapping generation framework, we show that production loans under credit rationing are not optimally extended towards firms because of issues with adverse selection. More stringent rationing in the credit market creates a distortion in the labor market by increasing adult wage rate and the demand for child labor. Lower availability of funds under stringent rationing coupled with increased demand for loans induces the high risk firms to replace adult labor by child labor. A switch of regime from credit rationing to revelation regime can clear such imperfections in the labor market. The equilibrium higher wage rate elevates the household consumption to a significantly higher level than the subsistence under credit rationing and therefore higher level of human capital development is assured leading to no supply of child labor.

Ex ante bargaining and ex post enforcement in trade credit supply: theory and evidence from China

If payment of goods is easily default, economic transaction may deeply suffer from the risk. This risky environment formed a mechanism that governs how economic transaction is realized, subsequently how trade credit is given. This paper distinguished ex ante bargaining and ex post enforcement, then modeled that bargaining power reduces trade credit ex ante, and ex post enforcement power and cash in hand of buyer can enhances both trade amount and trade credit in a presence of default risk. We modeled this relationship in order to organize findings from previous literature and from our original micro data on detailed transaction in China to consistently understand the mechanism governing trade credit. Then empirically tested a structure from the theoretical prediction with data. Results show that ex post enforcement power of seller mainly determines size of trade credit and trade amount, cash in hand of buyer can substitute with enforcement power; Bargaining power of seller is exercised to reduces trade credit and trade amount for avoiding default risk, but it simultaneously improves enforcement power as well. We found that ex post enforcement power consists of (ex ante) bargaining power on between two parties and intervention from the third party. However, its magnitude is far smaller than the direct impact to reduce trade credit and trade amount.

A puha költségvetési korlát szindrómája a kórházi szektorban = The soft budget constraint syndrome in the hospital sector

A kutatások eddig főképpen azt vizsgálták, hogyan jelenik meg a puha költségvetési korlát szindrómája a vállalati szférában és a hitelrendszerben. A jelen cikk a kórházi szektorra összpontosítja a figyelmet. Leírja az események öt főszereplőjének, a betegnek, az orvosnak, a kórházigazgatónak, a politikusnak és a kórház tulajdonosának motivációit és magatartásuk ellentmondásos jellegét. A motivációk magyarázzák, miért olyan erőteljes a túlköltési hajlam és a költségvetési korlát felpuhulásának tendenciája. A döntési és finanszírozási folyamatok minden szintjén felfelé hárítják a túlköltés és eladósodás terheit. A cikk kitér a különböző tulajdonformák (állami, nonprofit és forprofit nem állami tulajdonformák) és a puha költségvetési korlát szindrómájának kapcsolatára. Végül normatív szempontból vizsgálja a jelenséget: melyek a költségvetési korlát megkeményítésének kedvező és kedvezőtlen következményei, és hogyan tükröződnek a normatív dilemmák az események résztvevőinek tudatában. ___________ Researches so far have examined mainly how the soft budget constraint syndrome appears in the corporate sphere and the credit system. This article concentrates on the hospital sector. It describes the motivations and the contradictory behaviour of the five main types of participant in the events: patients, doctors, hospital managers, politicians, and hospital owners. The motivations explain why the propensity to overspend and the tendency to soften the budget constraint are so strong. The burdens of overspending and indebtedness are pushed upwards at every level of the decision-making and funding processes. The article considers the connection between the soft budget constraint syn-drome and the various forms of ownership (state ownership and the non-profit and for-profit forms of non-state ownership). Finally, the phenomenon is examined from the normative point of view: what are the favourable and unfavourable consequences of hardening the budget constraint and how these are reflected in the consciousness of the participants in the normative dilemmas and events.

The EU ban on uncovered sovereign credit default swaps: assessing impacts on liquidity, volatility and price discovery

This article addresses the effects of the prohibition against naked CDS buying implemented by the European Union in November 2012. Three aspects of market quality are analyzed: liquidity, volatility, and price informativeness. Overall, our results suggest that the ban produced negative effects on liquidity and price informativeness. First, we find that in territories within the scope of the EU regulation, the bid–ask spreads on sovereign CDS contracts rose after the ban, but fell for countries outside its bounds. Open interest declined for both groups of CDS reference entities in our sample, but significantly more in the constraint group. Price delay increased more prominently for countries affected by the ban, whereas price precision decreased for these countries while increasing for CDSs written on other sovereign reference entities. Most notably, our findings indicate that hese negative effects were more pronounced amid reference entities exhibiting lower credit risk. With respect to volatility, the evidence suggests that the ban was successful in stabilizing the CDS market in that volatility decreased, particularly for contracts written on riskier CDS entities.

Auxin And Physical Constraint Exerted By The Perianth Promote Androgynophore Bending In Passiflora Mucronata L. (passifloraceae).

The androgynophore column, a distinctive floral feature in passion flowers, is strongly crooked or bent in many Passiflora species pollinated by bats. This is a floral feature that facilitates the adaptation to bat pollination. Crooking or bending of plant organs are generally caused by environmental stimulus (e.g. mechanical barriers) and might involve the differential distribution of auxin. Our aim was to study the role of the perianth organs and the effect of auxin in bending of the androgynophore of the bat-pollinated species Passiflora mucronata. Morpho-anatomical characterisation of the androgynophore, including measurements of curvature angles and cell sizes both at the dorsal (convex) and ventral (concave) sides of the androgynophore, was performed on control flowers, flowers from which perianth organs were partially removed and flowers treated either with auxin (2,4-dichlorophenoxyacetic acid; 2,4-D) or with an inhibitor of auxin polar transport (naphthylphthalamic acid; NPA). Asymmetric growth of the androgynophore column, leading to bending, occurs at a late stage of flower development. Removing the physical constraint exerted by perianth organs or treatment with NPA significantly reduced androgynophore bending. Additionally, the androgynophores of plants treated with 2,4-D were more curved when compared to controls. There was a larger cellular expansion at the dorsal side of the androgynophores of plants treated with 2,4-D and in both sides of the androgynophores of plants treated with NPA. This study suggests that the physical constraint exerted by perianth and auxin redistribution promotes androgynophore bending in P. mucronata and might be related to the evolution of chiropterophily in the genus Passiflora.

A FIRST CONSTRAINT ON THE THICK DISK SCALE LENGTH: DIFFERENTIAL RADIAL ABUNDANCES IN K GIANTS AT GALACTOCENTRIC RADII 4, 8, AND 12 kpc

Based on high-resolution spectra obtained with the MIKE spectrograph on the Magellan telescopes, we present detailed elemental abundances for 20 red giant stars in the outer Galactic disk, located at Galactocentric distances between 9 and 13 kpc. The outer disk sample is complemented with samples of red giants from the inner Galactic disk and the solar neighborhood, analyzed using identical methods. For Galactocentric distances beyond 10 kpc, we only find chemical patterns associated with the local thin disk, even for stars far above the Galactic plane. Our results show that the relative densities of the thick and thin disks are dramatically different from the solar neighborhood, and we therefore suggest that the radial scale length of the thick disk is much shorter than that of the thin disk. We make a first estimate of the thick disk scale length of L(thick) = 2.0 kpc, assuming L(thin) = 3.8 kpc for the thin disk. We suggest that radial migration may explain the lack of radial age, metallicity, and abundance gradients in the thick disk, possibly also explaining the link between the thick disk and the metal-poor bulge.
