The labor market effects of trade union heterogeneity

Empirical evidence suggests that the bargaining power of trade unions differs across firms and sectors. Standard models of unionization ignore this pattern by assuming a uniform bargaining strength. In this paper, we incorporate union heterogeneity into a Melitz (2003) type model. Union bargaining power is assumed to be firm-specific and varies with firm productivity. This framework allows us to re-analyze the labor market effects of (i) a symmetric increase in the bargaining power of all unions and (ii) trade liberalization. We show that union heterogeneity unambiguously reduces the negative employment effects of stronger unions. Firm-specific bargaining power creates a link between unionization and the entry and exit of firms, implying a reduction of the unions' expected bargaining power. Moreover, union heterogeneity constitutes an (un)employment effect of trade liberalization. If unions are most powerful in the high-productivity (low-productivity) firms, trade liberalization will increase (decrease) unemployment.     

Evolving Efficiency of Dually-Listed Indian Stocks: A Nonlinear Perspective

This paper examines the degree of efficiency of Indian ADRs and their underlying stocks trading in NSE/BSE from an adaptive markets hypothesis (AMH) perspective that is theoretically grounded in nonlinear serial dependence. For this purpose, the authors employ the windowed as well as the rolling hinich bicorrelation test procedures on ADRs and the underlying stocks issued by Indian firms such as, and limited to, Dr. Reddy’s Laboratories, HDFC Bank, ICICI Bank, Infosys, Wipro, Tata Motors, and Sterlite Industries. The study’s findings indicate that the degree of market efficiency witnessed at the level of individual scrips (ADRs or underlying domestic stocks) differs considerably from the degree of efficiency of the broader stock market in which such scrips trade. Further, the degree of efficiency witnessed amidst all US and Indian scrips considered for this study was found to be heterogeneous in nature and in-turn warrants a ranking approach. Lastly, the degree of efficiency witnessed in certain (not all) dually-listed Indian scrips was found to be homogenous across trading locations. However, this does not happen to be the case for all other dually-listed scrips considered for this study. The study’s findings bring to light the need for disaggregated, firm level market efficiency studies aimed at examining firm-level market efficiency at different trading locations and in-turn identifying the antecedents behind homogeneity (or lack-thereof) in firm-level market efficiency across multiple trading locations.

     

Home country bias in international emissions trading: Evidence from the EU ETS

We examine the pattern of allowance trades in the European Union Emissions Trading System (EU ETS) using highly disaggregated trading data and identify a significant and robust home market bias. Our results point to informational transactions costs that increase when trading across national borders. The existing trade pattern in goods and services explains two thirds of the home bias, with the remainder due to other causes. Our finding suggests that firms make use of existing trade networks to overcome search costs in bilateral allowance trade. Since the home bias differs across firms, it follows that marginal abatement costs are not equalized across market participants of the EU ETS.     

Antidumping and heterogeneous quality adjustment of multi-product firms: Evidence from Chinese exporters

This paper investigates the effect of antidumping on multi-product firms’ adjustment in export quality using highly disaggregated Chinese exports data at the firm-product-country level for the period 2000–2014. In response to antidumping, firms tend to upgrade the quality of their exports for targeted products in affected markets by product adjustment, with this effect being more pronounced for firms with ex ante higher product quality. Antidumping induces resource reallocation across firms for a product such that higher-quality firms upgrade the quality while lower-quality firms are unaffected, and reallocation across products within a firm with the quality of products of higher competency increasing more substantially under antidumping policy. Our paper contributes to our understanding on how a multi-product firm adjusts by reallocating resources across products in the face of trade policy shocks.     

Relative wages, labor specialization and bargaining patterns

The goal of this paper is to study the effects of centralized and decentralized bargaining patterns on wage inequality when there are two different types of labor, skilled and unskilled. We present two models where labor is specialized between firms, that is, there are two types of firms, each one employing one type of labor. We show that the revenue shares of the production factors in each type of firm and the union power are crucial determinants of the relative wage. In contrast, the relative expected wage is the same across models and bargaining patterns.     

Oligopolistic Competition, Technology Innovation, and Multiproduct Firms

Firms' proliferation behavior in a differentiated product market is studied using an oligopolistic competition model with multiproduct firms. The model has the following characteristics: (1) the elasticity of substitution across firm's own products and the elasticity of substitution across different firms are allowed to differ; (2) the product managers of the same firm behave cooperatively rather than independently; (3) the number of firms is determined by a free-entry condition and so is endogenous. If the elasticity of substitution across the firm's own products increases, it is shown that the firm proliferates less and the number of firms in the market increases. If the elasticity of substitution across different firms increases, firms proliferate more and the number of firms in the market decreases.     

Products and Productivity*

When firms make decisions about which product to manufacture at a more disaggregated level than observed in the data, measured firm productivity reflects both characteristics of the firm and attributes of the products that are non‐randomly chosen by the firm. This paper develops a model of industry equilibrium in which firms endogenously sort across products and characterizes the resulting bias in measured firm and aggregate productivity. Calibrating the model's parameters, we show that endogenous product selection can have quantitatively important effects on measured firm and aggregate productivity and their response to changes in parameter values.     

Entry,market turbulence and industry employment growth

This paper investigates the relationship between industrial dynamics in terms of firm entry, market turbulence and employment growth. Do entry of firms, the composition of industry dynamics (net entry) and market turbulence (entry and exit) influence industrial employment growth? This paper provides an empirical investigation, using unique data for 42 disaggregated Swedish industrial sectors during the period 1997–2001. It is hypothesised that the importance of entering firms, net entry and market turbulence may differ significantly across industries. A quantile regression method is used in order to detect industrial differences in the response to industrial employment growth. The empirical evidence shows that, on the one hand, firm entry and market turbulence have a positive effect on employment for fast growing industries and that the effect is larger for high growth industries. On the other hand, the composition of industry dynamics in terms of net entry rates has a more dispersed effect across all industries, even though the effect of net entry is larger for high growth industries.     

Sudden stops, financial frictions, and labor market flows: Evidence from Latin America

While the aggregate effects of sudden stops and international financial crises are well known, the disaggregated channels through which they work are not well explored yet. In this paper, using job flows from a sectoral panel dataset for four Latin American countries, we find that sudden stops are characterized as periods of lower job creation and increased job destruction. Moreover, these effects are heterogeneous across sectors: we find that when a sudden stop occurs, sectors with higher dependence on external financing experience lower job creation. In turn, sectors with higher liquidity needs experience significantly larger job destruction. This evidence is consistent with the idea that dependence on external financing affects mainly the creation margin and that exposure to liquidity conditions affects mainly the destruction margin. Overall, our results provide evidence of financial frictions being an important transmission channel of sudden stops and in the restructuring process in general.     

Decentralization in Pollution Permit Markets

A pollution permit market is decentralized when firms are allowed to trade permits across time, regions or pollutants. Using a model in which firms have better information about their abatement costs than a regulator, we develop a comparative advantage formula that delineates whether or not pollution permit markets should be decentralized. When the damage from pollution is described by a separable function, the formula implies a simple sufficient condition for not allowing decentralization.     

Subsidy competition and imperfect labor markets

This study presents a two‐country model of subsidy competition for manufacturing firms under labor market imperfections. Because subsidies affect the distribution of firms, subsidies influence unemployment rates and welfare in both countries. We show that when labor market frictions are high, subsidy competition is beneficial, although subsidies under subsidy competition are inefficiently high. In the coordinated equilibrium, the supranational authority provides a subsidy to firms that equal the expected total search costs, which increases the number of firms relative to laissez‐faire and improves welfare relative to laissez‐faire and subsidy competition. Finally, we find that a rise in a country's labor market frictions raises the equilibrium subsidy rate, affects unemployment rates, and lowers welfare.     

Trade liberalization and markups: Micro evidence from China

This paper presents evidence from highly disaggregated Chinese firm-product data that, given productivity, input tariff reductions induce an incumbent importer/exporter to increase product markups. We further investigate empirically the mechanisms underlying this trade liberalization effect, and find that input tariff reductions decrease marginal costs, and their effects on markup adjustments are more profound among firms with higher import dependence. Moreover, we exploit unique features of Chinese data by comparing results for two trade regimes: ordinary trade (wherein firms pay import tariffs to import) and processing trade (wherein firms are not subject to import tariffs). While the aforementioned trade liberalization effects and mechanisms only apply to ordinary trade, processing trade samples are used in a placebo test. The paper also shows that more productive firms charge higher markups for products. All these findings are robust to alternative markup measures including one estimate using physical-quantity output data, different production function specifications, a subsample consisting only of pure exporters, and estimations based on our theoretical derivations.     

Equity-settled share-based payments and their (strategic) use under asymmetric information

Share-based payments are of widespread use in today's economy. Consulting firms are increasingly accepting equity compensation for their services (particularly from startups) and many governments provide fiscal incentives to support this choice. Likewise, profit-sharing licensing is an on-trend business practice by innovative firms and patent holders when transferring their technology to interested adopters. This paper unveils strategic considerations according to which an agent/seller designs its optimal policy in regard to the equity share to request in exchange for its service, technology, or trademark. The model assumes a fringe of interested users/customers differentiated by both the support they need from the seller and the value of the underlying relationship; and also holding an informational disadvantage on their own type. Given the seller's cost configuration, equilibrium outcomes entail entering a profit-sharing relationship either with the high-type customers only or with all customers. Yet, in this case, equity-based payment claims are —for rent extraction purposes— common (i.e., not differentiated) across types.     

Absorptive capacity and quality upgrading effect of OFDI: Evidence from China

Does outward foreign direct investment (OFDI) from developing countries affect firms' competitiveness in international markets through quality upgrading of export? Using highly disaggregated Chinese product level data and the firm level information on overseas investment from 2000 to 2006, we attempt to provide an answer to this question. We employ the propensity score matching approach and difference-in-differences specification to deal with the sample selection bias and the potentially endogenous problem in inferring the causal effect of OFDI on quality upgrading. The results reveal that investment abroad could significantly push China export up on quality ladders. The firms with OFDI have higher quality products when compared with the firms remaining invest in their home country at product-export destination level. This quality upgrading effect is more pronounced where firms export to high-income countries. Furthermore, we show that the learning mechanism works and the absorptive ability of firms could reinforce the quality upgrading effect of OFDI. The learning mechanism also works for the firms with difference OFDI strategies.     

Chinese overseas M&A performance and the Go Global policy1

It is well known that government plays an important role in the business activities of Chinese firms. Less certain is the effect this influence has on the wealth of those firms’ shareholders. We contribute to the literature by analysing stock market reactions to announcements by Chinese firms of overseas mergers and acquisitions (OMAs). OMAs are of particular interest because there can exist a conflict between the interests of the public sector in acquiring overseas assets, and the interests of the private sector in maximizing shareholder wealth. Our main dataset consists of 213 observations of 157 OMA events that occurred between 1994 and 2009, using share market returns from the Shanghai, Shenzhen, Hong Kong and US markets. The aggregation of share price data across multiple markets, and the listing of firms in multiple exchanges, raise econometric issues for the standard event‐study methodology. To address these, we use a new, feasible generalized least squares (GLS) procedure developed by Gu and Reed (2012) . On the basis of an analysis using both aggregated and disaggregated samples, and of daily and cumulative abnormal returns, we find consistent evidence that (i) Chinese OMAs have not lowered the wealth of shareholders of Chinese acquiring firms, and (ii) shareholders of Chinese acquiring firms have not fared worse under under China's ‘Go Global’ policy of encouraging outward investment by Chinese firms.     

Recognising investment opportunities at the onset of recoveries

This model focuses on the decision to invest in novel fields of activity. Making such decisions implies that managers recognise the potentialities of emerging technological patterns, which is not a trivial ability. Ultimately, it depends on the mental categories that they developed through their working life, which may or may not be appropriate to the situation that they are facing.In this article, investment decision-making is modelled by means of an unsupervised neural network. Its neurons represent firms as decision-makers and their weights correspond to the coefficients of a disaggregated, flexible accelerator.The ensuing formalisation accounts for the often observed inability of firms that used to be highly successful with a certain technology to recognise and exploit novel, substitute technologies. Within economic theory, this formalisation may be seen as a possible micro-foundation for the beginning of recoveries in Goodwin's model of the business cycle.     

DYNAMICS OF PRODUCTIVITY AND COST OF LABOUR IN ITALIAN MANUFACTURING FIRMS

This paper studies the impact of size on labour cost and productivity for Italian manufacturing firms. The distributions of both labour cost and productivity display a wide support, even when disaggregated by sector of industrial activity. Further, both labour cost and productivity, when considered alone, are growing with the size of the firm. We investigate this relationship on a new set of data and we are able to show that once productivity differences among firms have been accounted for, size still retains a positive effect on cost of labour in most of the sectors considered.     

Medium,message and advertising effectiveness in the Greek processed meats industry

This paper examines the effectiveness of advertising in the fast-growing Greek processed meats sector using an unbalanced panel data set of 34 firms during the period 1983–1997. In analysing the relationship between firms' sales and advertising this study differentiates between the type/content of the advertising message and the medium used to communicate it. Advertising expenditures are disaggregated into company and product campaigns in television, radio, and print media. Empirical results strongly reject the hypothesis of homogeneous consumer response to all kinds of advertising that is implicit in studies that aggregate advertising expenditures. The results also indicate an inefficient allocation of advertising resources by the firms of the sector; advertising in the least utilized print media was determined to be by far the most effective strategy during the study period.     

The role of extensive and intensive margins and export growth

We investigate and compare countries' export growth based on their performance at the extensive and intensive export margins. Our empirical approach is motivated by an extension to the Melitz (2003) model of heterogeneous firms in which exporters are subject to a one-time sunk cost and also a per-period fixed cost. With imperfect information a firm may enter export markets but shortly exit when it learns its per-period fixed costs. We apply this insight to disaggregated export data and confirm that indeed most export relationships are very short lived. We then show that the survival issue is a significant factor in explaining differences in long run export performance. We find that developing countries would experience significantly higher export growth if they were able to improve their performance with respect to the two key components of the intensive margin: survival and deepening.     

The firm demand for liquid assets in an inflationary environment

Measures of inflation and the price level are added to the standard model of liquid asset demand and estimated with cross-section data on Brazilian manufacturing firms over a four-year period characterized by substantial inflation (annual rates of 19, 23, 34 and 35%). Results indicate that economies of scale exist in a model that is stable over time. Interest rates have a strong and elastic impact on liquid asset demand when inflation is explicitly controlled for although this result is not consistent across all subsets of data used. The usual assumption of a unitary price level elasticity of liquid asset demand is rejected and firms appear to conserve on liquid asset holdings as the rate of inflation increases suggesting more careful management of payments flows. Some of these findings contradict those of Ungar and Zilberfarb (1980). There are also some difference in behaviour across ownership groups: Brazilian firms do not exhibit economies of scale while multinationals do; and Brazilian firms adjust actual to desired balances faster than multinational firms.
