Flexible Labor Regulations and Informality in Egypt

Do more flexible labor market regulations reduce informal employment in formal firms? This paper examines the effects of changes in labor regulations on the incidence of formal employment. Using the case of Egypt, we study the effects of the introduction of more flexible labor regulations in 2003 on the probability that non‐contractual workers will be granted a formal employment contract. To identify the effect of the law and control for potential confounding factors, we use a difference‐in‐difference estimator that measures the difference in the pre‐ and post‐law probability of obtaining a formal contract across a treatment group of non‐contractual workers initially employed in formal firms and a comparison group of non‐contractual workers initially employed in informal firms. The latter serve as a useful comparison group since informal firms are unlikely to formalize as a result of the law, so that the only way their workers can become formal is to move to another firm. Our findings show that the passage of the new labor law did in fact increase the probability of transitioning to formal employment for non‐contractual workers employed in formal firms by about 3–3.5 percentage points, or the equivalent of at least a fifth of informal workers in formal firms.     

最优农业契约与中国农业产业化模式

本文在一个统一的关系契约分析框架下,比较了单期和多期条件下"农户+市场"、"龙头企业+农户"和"龙头企业+农场"三种主要的农业产业化模式及其衍生模式的生产效率,并分析了产权、声誉、抵押和风险态度对最优农业契约的影响。我们的分析表明,在单期条件下,由于契约不完全和敲竹杠效应,所有模式都无法实现最优效率;在多期条件下,如果贴现率足够低,"龙头企业+农户"和"龙头企业+农场"这两种模式都可以实现最优效率;如果市场价格波动比较大,则"龙头企业+农场"模式优于"龙头企业+农户"模式。我们还分析了农户的转售成本对契约效率的影响,并提供了支持本文结论的典型案例。     

The Behaviour of Declining Industries

This paper examines how the prospect of imminent exit by a competitor in a declining industry affects the market behaviour of that industry prior to exit. We show that 'survivor' firms have an incentive to increase their holdings of inventories and to hold excess capacity before exit occurs. Preparation for the failure of a rival will also involve increasing output. This will push down the market price and may hasten the rival firm's demise. The welfare consequences of these actions are mixed but can be very different from the same actins in a growing or stable industry. In particular, holding excess capacity or increased inventories may be procompetitive.     

Monetary Transmission and Inventory: Evidence from Japanese Balance-Sheet Data by Firm Size

I analyse the response of inventories and short-term debts to monetary policy using disaggregated data on Japanese manufacturing firms classified by firm size. I find that monetary contraction decreases the inventories of large firms; however, inventories of small and medium firms increase considerably for the first several quarters. This implies that in a subcontracting system small and medium subcontractors serve as a buffer and alleviate the monetary shocks felt by their large parent firms. Moreover, inventory build-ups are financed by increases in accounts payable. I also find that for small firms land asset is important in easing credit conditions and increasing inventories.

Distress cost and corporate financing policy: evidence from the equity options market

This study examines the link between distress cost and corporate financing policy through the lens of the equity options market. Four features stand out. First, the cost of distress is comparable to the tax shield from debt financing. Second, the results provide evidence that ordinary least-squares estimates understate the impact of market leverage on default risk. Third, consistent with the information models of debt maturity, firms with higher default probability use more long-term debt. Finally, more distressed firms rely on secured debt to a greater extent. Overall, the results support the trade-off theory of capital structure.     

治理机制何时有助于联盟成功——基于不确定性视角的研究

基于交易成本理论和关系交换理论，采用比较研究法，探讨契约治理与关系治理对联盟成功的差异化影响并识别边界条件。运用410家联盟企业调研数据进行实证研究，结果表明关系治理比契约治理更有助于企业实现联盟成功，且这种影响效应随着联盟情境不同而发生改变。当联盟外部环境不确定性程度加深时，企业会更加依赖于关系治理而非契约治理实现联盟成功；当联盟伙伴行为不确定性程度加深时，企业选择契约治理比依赖关系治理更容易实现联盟成功。研究结论可为联盟企业在不同情境条件下选择恰当治理机制并实现联盟成功提供理论指导。     

Assessing the relative efficiency of agricultural production units in the Blackland Prairie,Texas

The hypotheses that endogenous credit constraints based on fluctuating asset values and cash flow prolong and accentuate US cattle cycles; and that more diversified cow-calf firms are less affected by this phenomenon are tested. Breeding cattle inventories are an interesting example to study credit constraints because they are among the most cyclical of economic time-series, firms have heterogeneous diversification levels, and they avoid many of the problems with previous investment-cash flow sensitivities studies noted by Kaplan and Zingales. The results are consistent with earlier credit constraint studies, i.e. breeding cattle inventories are sensitive to shifting credit constraint regimes and cow-calf firms with higher diversification levels are less affected by credit constraints.     

Contractual distortions in a market with frictions

This paper analyses contract design in a decentralized market environment with frictions. While principals (e.g., firms) have all contractual power, their market power is constrained as agents (e.g., workers) can choose to wait and search for better offers. We find that results depend crucially on how market frictions affect agents’ utilities. With type-independent costs of search and waiting, equilibrium contracts are always first-best. If agents are impatient and discount future payoffs, however, distortions vanish only gradually. In the latter case, we also characterize equilibrium offers and show that the market exhibits two types of externalities, both of which are absent in the case of type-independent costs of search.     

Information and transparency in wholesale electricity markets: evidence from Alberta

We examine the role of information transparency in Alberta’s wholesale electricity market. Using data on firms’ bidding behavior, we analyze whether firms utilize information revealed in near real-time through the Historical Trading Report (HTR), which is released 10 min after each hour and contains a complete (de-identified) list of every firms’ bids into the wholesale market from the previous hour. We demonstrate that firms are often able to identify the offers of specific rivals by offer patterns adopted by those firms. For one of these firms, these patterns are associated with higher offer prices. This is consistent with allegations by Alberta’s Market Surveillance Administrator that firms may be utilizing unique bidding patterns to reveal their identities to their rivals to elevate market prices. We show that certain firms respond to rival offer changes with a lag consistent with responding to information revealed through the HTR, and that they respond differently to different firms, suggesting that they are able to infer identification.     

The institutional environment for multinational investment

This article posits that the effect of political hazards onthe choice of market entry mode varies across multinationalfirms based on the extent to which they face expropriation hazardsfrom their potential joint-venture partners in the host country(the level of contractual hazards). As political hazards increase,the multinational faces an increasing threat of opportunisticexpropriation by the government. Partnering with host-countryfirms that possess a comparative advantage in interactions withthe host-country government can safeguard against this hazard.However, as contractual hazards increase, the potential benefitto the joint-venture partner of manipulating the political systemfor it's own benefit at the expense of the multinational increasesas well, thereby diminishing the hazard-mitigating benefit offorming a joint venture. A two-stage bivariate probit estimationtechnique is used to test these hypotheses on a sample of 3,389overseas manufacturing operations by 461 firms in 112 countries.     

Pre-commercial procurement,procurement of innovative solutions and innovation partnerships in the EU: rationale and strategy

We discuss public procurement instruments for acquiring innovation, focusing on the European Pre-commercial Procurement, Procurement of Innovative Solutions and Innovation Partnerships. We analyse, in particular, how firms’ innovation incentives are affected by: (i) economies of scope and externalities between R&D and large-scale production; (ii) the degree of specificity of the innovation; (iii) the presence of Small and Medium Enterprises in the market and the level of market competition; (iv) the risk of market foreclosure and supplier lock-in. Our study contributes to the literature on incentives in demand-side innovation policy by tapping into the contractual design features and by offering relevant implications for academics and policy-makers.     

Credit ratings and corporate disclosure behaviour: evidence from regulation fair disclosure in Korea

This article provides evidence that firms with high market expectations disclose more information to investors, utilizing the fair disclosure regulation in Korea to proxy for their disclosure choices. This finding is consistent with the argument that in order to retain their dominant positions, highly evaluated firms are more concerned about the market’s perception of them as providers of timely and detailed disclosure. We also find that the impact of market expectations on disclosure is more pronounced for chaebol firms. Combined with prior research on the relationship between firm performance and voluntary disclosure, we provide important implications for the determinants of corporate disclosure     

Microcredit market structure and financing obstacles for micro firms

Using rich survey data of micro firms in Eastern Europe and Central Asia, I analze the effect of recent changes in microcredit market structure on perceived financing obstacles. Controlling for country, time and firm characteristics, lower microcredit market concentration is associated with firms reporting financing as a more severe obstacle to their operations. This indicates that rising competition between microfinance institutions may have led to reduced financial access. The results are consistent with information‐based theoretical predictions that lenders with less market power have weaker incentives to invest in lending relationships with opaque firms and that greater competition aggravates borrower screening.     

Born like China,growing like China

This paper studies the effects of China's one‐child policy on saving and foreign reserve accumulation. Fertility control increases the saving rate both by altering saving decisions at the household level, and by altering the demographic composition of the population at the aggregate level. I show that demographically induced changes in saving explain the build‐up of a large foreign surplus in China. As in Song, Storesletten, and Zilibtti (2011), the model features contractual and financial market imperfections. Government‐owned firms are less productive but have full access to the credit market. Entrepreneurial firms are more productive but face credit constraints. As labour switches from less productive to more productive firms, demand for domestic bank borrowing decreases. As saving increases while demand for loans decreases, domestic savings are invested abroad, generating a foreign surplus. The model predicts that China's foreign reserve accumulation will soon begin to slow down in response to recent relaxation of the one‐child policy.     

Changes in income inequality and the black market premium

Italian firms are top users of trade credit in an international comparison. The paper offers some clues to the determinants of this stylized fact exploiting the answers of about 1900 manufacturing firms on a wide range of contractual features, separately for domestic and foreign customers. The main finding of the univariate analysis is that, with the almost totality of transactions made on credit, there is no evidence that this way of financing is more expensive than loans. An econometric investigation shows that discounts offered have the expected effect of reducing payment delays mostly for customers located abroad, where customary credit periods are shorter and creditors’ rights protection is more effective. The result is consistent with the poor explanatory power of discounts received in regressions for the trade debt period of domestic firms.     

Market Share, Market Value and Innovation in a Panel of British Manufacturing Firms

This paper examines the empirical relationship between technological innovations, market share and stock market value. New developments in the estimation of dynamic count data models are used to control for unobserved firm specific heterogeneity. We find a robust and positive effect of market share on observable headcounts of innovations and patents although increased product market competition in the industry tends to stimulate innovative activity. Furthermore, the impact of innovation on market value is larger for firms with higher market shares. We argue that our results are consistent with models where high market share firms have incentives to pre-emptively innovate.     

Trade Marks and Performance in Services and Manufacturing Firms: Evidence of Schumpeterian Competition through Innovation

We develop Lancaster's model of consumer behaviour under product differentiation to analyse Schumpeterian creative destruction. Launching new products with novel characteristics enables firms to temporarily steal market share from rivals. Product launch is monitored by using trade marks, patents and research and development. The dataset covers a large sample of UK service and manufacturing firms. We find that stock market value is positively associated with own trade mark activity and trade mark‐active firms achieve significantly higher value‐added. Greater trade mark activity by competitors reduces net output of firms, but raises their stock market value. This is consistent with the Schumpeterian process of competition through innovation.     

Production and price smoothing by inventory adjustment?

The present paper examines the role of inventories for the short run adjustment behavior of firms. A theoretical model of a monopolistic firm carrying inventories that includes costs of adjusting output is examined. The model is tested empirically by using business survey data collected by the IFO-Institute, Munich. It is shown, that if data on individual firms are used and econometric estimation techniques are applied that properly take this into account, the estimates derived are fully compatible with the appealing idea of production smoothing by inventories.
