Empirical studies of trade marks – The existing economic literature

This paper surveys empirical studies employing trade mark data that exist in the economic literature to date. In the introductory section we summarise the theory of trade marks. Section 2 documents the use of trade marks by firms of different size and industry and by firms in several advanced countries, including Australia, the UK, and the USA. Section 3 reviews various attempts to gauge the function of a trade mark as an indicator of innovation and product differentiation. Section 4 surveys studies that have demonstrated firms' incentives to use trade marks, including transferring information to consumers, realising synergies between different types of intellectual property rights, strategies to raise rivals' costs and using trade mark portfolios as debt collateral. In Section 5, we provide an overview of the importance of trade-mark-use for firm survival and the association of trade marks with several dimensions of firm performance, including productivity and their ability to generate well-paid jobs.     

THE PROPAGATION OF UNCERTAINTY SHOCKS: ROTEMBERG VERSUS CALVO

This article studies the effects of uncertainty shocks on economic activity, focusing on inflation. Using a vector autoregression, I show that increased uncertainty has negative demand effects, reducing GDP and prices. I then consider standard New Keynesian models with Rotemberg-type and Calvo-type price rigidities. Despite the belief that the two schemes are equivalent, I show that they generate different dynamics in response to uncertainty shocks. In the Rotemberg model, uncertainty shocks decrease output and inflation, in line with the empirical results. By contrast, in the Calvo model, uncertainty shocks decrease output but raise inflation because of firms' precautionary pricing motive.     

Are the Energy Efficiency Technologies efficient?

This paper investigates a rather neglected issue regarding the impact of Energy Efficiency Technologies (EETs) on firms' productive performance. Possible influences may arise in the context of internal cost of adjustment, learning by doing effects and the capital vintage. A unique dataset was used which has resulted from a survey carried out among a sample of Greek EET adopters in the manufacturing sector. An econometric framework based on nested non-neutral frontiers, was developed to estimate the influence and the decomposition of EETs on firms' productive performance. The empirical findings reveal that the EETs affect positively the firms' technical efficiency and negatively the deterministic part of the frontier. Significant variations among industries and size groups appear to be present. Some policy implications are derived based on the empirical evidence supporting a mix of energy and technology directions.     

Corruption and the effects of economic freedom

The prediction that economic freedom is beneficial in reducing corruption has not been found to be universally robust in empirical studies. The present work reviews this relationship by using firms' data in a cross-country survey and argues that approaches using aggregated macro data have not been able to explain it appropriately. We model cross-country variations of the microfounded economic freedom–corruption relationship using multilevel models. Additionally, we analyse this relationship by disentangling the determinants for several components of economic freedom because not all areas affect corruption equally. The results show that the extent of the macro-effects on the measures of (micro)economic freedom for corruption, identified by the degree of economic development of a country, can explain why a lack of competition policies and government regulations may yield more corruption. Estimations for Africa and transition economy subsamples confirm our conjectures.     

Skills scarcity and export intensity

We describe a model of trade with skills-based product differentiation and non-proportional trade costs that predicts a positive correlation between firms' export intensity, the price of their exports and the wages they pay to their workers. In equilibrium, firms that employ workers with comparatively scarcer skills export a larger proportion of their output, pay higher wages and charge higher prices. In line with empirical evidence, the model predicts that trade liberalization can cause the distribution of earnings to become more polarized, with patterns that reflect the heterogeneous effects of trade liberalization on firms' export performance.     

How to Increase R&D in Transition Economies? Evidence from Slovenia

The recent initiative of the European Union Lisbon Agenda to increase levels of R&D investment is addressed by studying the determinants of R&D investment in one of the recent EU entrants, Slovenia. Previous empirical literature—mainly cross‐sectional in nature—has tested the demand–pull hypothesis and found that overall R&D expenses may be driven by output demand. We use a panel of more than 150 of the largest Slovene firms over the period 1996–2000, modeling firms' R&D behavior within an error‐correction framework and estimating it in a system GMM specification. While we find that sales have a significant role in inducing R&D expenditures, we also show that the availability of internal funds and wage bargaining represent important factors determining R&D expenses. Moreover, firms owned by insiders (workers and/or managers) and/or firms with dispersed ownership (small shareholders) display higher R&D investments than firms owned by privatization investment funds or by other firms.     

The determinants of capital structure in transitional economies

This study investigates whether capital structure determinants in emerging Central and Eastern European (CEE) countries support traditional capital structure theory developed to explain western economies. The empirical evidence suggests that some traditional capital structure theories are portable to companies in CEE countries. However, neither the trade-off, pecking order, nor agency costs theories explain the capital structure choices. Companies do follow the modified “pecking order.” The factors that influence firms' leverage decisions are the differences and financial constraints of banking systems, disparity in legal systems governing firms' operations, shareholders, and bondholders rights protection, sophistication of equity and bond markets, and corporate governance.     

FDI,Industry Heterogeneity and Employment Elasticity in China

We investigate the different impacts of foreign direct investment (FDI) on employment elasticity with China's firm level data from 1998 to 2007. Our analysis shows that the inclusion of FDI does significantly affect firms' employment elasticity when facing wage, capital and output shocks. These effects vary dramatically across industries with different factor intensities and export status. Specifically, we find that non‐exporters with FDI tend to increase employment elasticity more than exporters when wage, capital input or output changes. However, FDI firms that are engaging in labor‐intensive production tend to have larger output and capital input elasticity of employment while smaller wage elasticity of employment. Our findings help to explain the contradicting results in existing literature and provide important references for China's policy makers to design proper industry policies towards FDI.     

PRODUCTIVITY OR UNEXPECTED DEMAND SHOCKS: WHAT DETERMINES FIRMS' INVESTMENT AND EXIT DECISIONS?

We investigate the roles played by unexpected demand shocks, besides productivity, on firms' capital investment and exit decisions. We propose a practical approach to recover unexpected firm‐level demand shocks using inventory data. The recognition of demand shocks and inventory also improves the productivity estimation. The empirical results indicate that although productivity and demand shocks are both significant factors determining firm behavior, the former is more dominant for investment decision and the latter is more salient for firm exit. These findings confirm that unexpected demand shocks, besides persistent productivity, are important factors when analyzing capital investment and firm exit decisions.     

DYNAMIC ENTRY WITH DEMAND AND SUPPLY SIDE SPILLOVERS

Supply side spillovers have been used to explain firms' entry behavior in the pharmaceutical industry. In contrast, demand side spillovers have received less attention. This paper identifies supply and demand spillovers using a dynamic model of strategic interaction. The results indicate that demand side spillovers are more significant than the supply side spillovers to generic drug firms, and the demand side spillovers increase a firm's market share by 3%–4% on average in subsequent market entry. In addition, with supply side spillovers alone, lowering entry barriers can increase future entry rates, while in the case of demand side spillovers, lowering entry barriers will have the opposite effect.

Monetary Policy, Agency Costs and Output Dynamics

This paper examines the role of financial market imperfections for output reactions to nominal interest rate shocks. Empirical evidence shows a hump-shaped impulse response function of output and suggests that credit supply co-moves with output. A monetary business cycle model with staggered price setting is presented where the firms' outlays for capital and labor must be covered by the sum of net worth of entrepreneurs and loans in the form of debt contracts. These properties are shown to generate a hump-shaped impulse response of output, which takes on the smooth and persistent appearance of the empirical output response when nominal wages are set in a staggered way, too.     

DO INVESTMENT‐SPECIFIC TECHNOLOGICAL CHANGES MATTER FOR BUSINESS FLUCTUATIONS? EVIDENCE FROM JAPAN

The observed decline in the relative price of investment goods to consumption goods in Japan suggests the existence of investment‐specific technological (IST) changes. We examine whether IST changes are a major source of business fluctuations in Japan, by estimating a dynamic stochastic general equilibrium model using Bayesian methods. We show that IST changes are less important than neutral technological changes in explaining output fluctuations. We also demonstrate that investment fluctuations are mainly driven by shocks to investment adjustment costs. Such shocks represent variations of costs involved in changing investment spending, such as financial intermediation costs. We find that the estimated series of the investment adjustment cost shock correlates strongly with the diffusion index of firms' financial position in the Tankan (Short‐term Economic Survey of Enterprises in Japan). Therefore, we argue that the large decline in investment growth in the early 1990s was due to an increase in investment adjustment costs stemming from firms' financial constraints after the collapse of Japan's asset price bubble.     

COMPETITION, PARALLEL IMPORTS AND COST-REDUCING INNOVATION

Incorporating parallel imports (PI), we develop a two‐country two‐firm model which relates to the incentives for cost‐reducing innovation. We show that PI may facilitate or inhibit the manufacturers' incentives to innovate. In particular, PI could encourage both firms' innovations. The difference between the manufacturer's profits under successful innovation and failed innovation is either a U‐shaped curve or an inverted U‐shaped curve in terms of the cost of engaging in PI. As these differences reflect the manufacturers' incentive to innovate, the variations in R&D investment depend on transportation cost, and firms' marginal costs before and after successful innovations.     

Price setting behaviour in Latvia: Econometric evidence from CPI micro data

This paper discovers the driving forces behind Latvian firms' decisions to adjust prices by using various panel logit models, which explain the probability of observing price change by a broad set of exogenous variables. The results show that the consumer price formation in Latvia is a combination of both state-dependent and time-dependent behaviours. On the one hand, frequency of price changes depends on inflation, demand conditions, and the size of last price changes. On the other hand, we observe some elements of time-dependent price setting like price truncation and strong seasonal pattern. We also find several important differences in the price setting behaviour in cases of price increases and decreases. The fact that frequency of price changes in Latvia depends on inflation as well as demand and supply conditions allows for faster price adjustment process in the event of high distortions in the economy.     

The impact of productivity and demand shocks on structural dynamics: Evidence from Austrian manufacturing

Based on Pasinetti's model of structural dynamics we develop an empirical identification strategy for aggregate and sectoral labor productivity and demand shocks in a structural vector autoregressive model with long-run restrictions. Impulse response analysis shows that we can distinguish four patterns of the effects of changes in demand and productivity growth on sectoral output growth. For some industries demand is indeed the factor driving sectoral growth. Labor productivity and demand shocks are closely associated with the growth rates of employment and output across industries. However, there is less correlation with entry and exit. This suggest that structural change within and between industries may have quite different determinants.     

Technology Adoption,Export Status,and Skill Upgrading: Theory and Evidence

This paper develops a model of trade that features heterogeneous firms, technology choice and different types of skilled labor in a general equilibrium framework to explain within‐industry increase in the relative demand for skilled workers. Its main contribution is to investigate the impact of firms' export and technology choice decisions on skill upgrading. Only firms in the upper range of the productivity distribution produce for the foreign market using high‐technology. Since this technology is skilled‐biased, exporters that resort to modern technologies are more skill intensive. Empirical evidence is also provided to support the model's main predictions using plant‐level panel data from Chile's manufacturing sector (1990–1999).     

Price Dynamics in Repeat-Purchase Markets*

A retail market in which customers repeat purchase is modelled. When customer movement between firms is sluggish, price overshooting characterizes firms' optimal response to demand or cost shocks. Thus retail prices would be predicted to be more variable than wholesale prices, a prediction at variance with empirical evidence. Uncertainty in demand and customer imperfect information are introduced into the model to attempt to reconcile this inconsistency between theory and evidence. The introduction of demand uncertainty actually increases the magnitude of price overshooting. By contrast, the introduction of imperfect customer information reduces the variability in retail prices.     

A micro data approach to the identification of credit crunches

This article presents a micro data approach to the identification of credit crunches. Using a survey among German firms which regularly queries the firms' assessment of the current willingness of banks to extend credit, we estimate the probability of a restrictive loan supply policy by time taking into account the creditworthiness of borrowers. Creditworthiness is approximated by firm-specific factors, e.g. the firms' assessment of their current business situation and their business expectations. After controlling for the return on the banks' risk-free investment alternative, which is also likely to affect the supply of loans, we derive a credit crunch indicator, which measures that part of the shift in the loan supply that is neither explained by firm-specific factors nor by the opportunity costs of providing risky loans.     

Evidence on inflation–output trade-off in developing and industrial countries

This paper subjects Lucas's output–inflation trade-off study to further empirical investigation. The cross-country study divides the 111 countries covered into 90 developing countries and 21 advanced countries. Lucas's proposition is that volatility of aggregate demand growth should reduce the impact of aggregate demand growth on the cyclical output and the implication of this is that there is no output–inflation trade-off in line with the natural rate theory. We employ annual data over periods that fall between 1958 and 1985 in order to conduct the test. Our findings suggest that Lucas's proposition is valid for developed economies but not for developing economies.     

Are we ignoring supply shocks? A proposal for monitoring cyclical fluctuations

Although there are several mechanisms within theoretical models acknowledging that supply shocks can account for an important part of output fluctuations, even in the short-run, policy practitioners continue endorsing the idea that only demand shocks explain them. This article provides empirical evidence on several Latin American countries and the USA to show that the share of output variance explained by supply shocks in the short-run is substantial. It also offers a more agnostic implementation of the Blanchard–Quah type of structural analysis that focuses on policy evaluation. For this purpose, we propose constructing two indicators out of the historical decomposition of shocks: the goods market unbalance (GMU) and the total cyclical fluctuations (TCF). While GMU is an excess demand measurement that reveals the scope of the distortions caused by shocks, TCF, combined with GMU, helps to understand what type of shock is predominantly explaining (output and inflation) fluctuations. These two pieces of information provide a very different diagnosis than traditional output gaps and should guide monetary policy interventions more adequately. The agnosticism of this proposal has two aspects: the use of a different identification strategy and the assessment of the effects of both supply and demand shocks on output.
