Niche firms,mass markets,and income across countries: Accounting for the impact of entry costs

I develop a model of monopolistic competition in which I distinguish between niche markets and mass markets, in the spirit of Holmes and Stevens, 2014. Firms choose between entering a small niche market with high markups or a large mass market with low markups. Entry costs and other distortions have a much greater impact on output in the niche market as the gains to specialization are high, relative to the mass market where varieties are highly substitutable. Calibrated to match data from U.S. manufacturing, the model generates an elasticity of total factor productivity with respect to entry costs almost twice that in a model that abstracts from heterogeneous markets. I use data on entry costs across countries to show entry costs alone can account for 23 percent of the cross-country variation in income per worker.     

经济新闻自由度与资本市场的有效性

从金融经济学"效率市场假说"的理论与实证研究结果角度分析经济新闻自由对于金融市场发展的影响后认为,经济新闻自由是实现效率市场的宏观机制之一;只有充分的经济新闻自由,信息才能迅速而充分地扩散到市场,并被包括到资产的价格中,从而实现效率市场,促进资本市场的发展。利用世界银行各国股市市值数据与"自由之家"对各国新闻自由度的评定数据进行的统计分析表明,经济新闻自由与股市市值之间具有显著的正相关性。     

Platform market competition with endogenous side decisions

This paper develops a framework to analyze platform competition in two‐sided markets in which agents endogenously decide on which side of a platform to join. We characterize the equilibrium pricing structure and perform a comparative statics analysis on how the distribution of agents’ preferences affects the platforms’ profits. We also show that the market equilibrium under profit‐maximizing platforms leads to the first best social surplus, which illustrates the importance of the price mechanism to induce more balanced participation across the two sides. This framework can be applied to analyze market competition for “rental” or “sharing” platforms. In addition, we extend our analysis to consider an initial investment stage, which makes participants the owner of some durable goods to rent out.

Commonality in liquidity among Middle East and North Africa emerging stock markets: Does it really matter?

This study investigates commonality in daily liquidity among 11 emerging stock markets from the Middle East and North Africa from January 2005 to June 2017. First, we test long memory in liquidity in these markets. Second, we select a number of factors eligible to affect liquidity commonality among local, regional and global factors. We find that regional and US factors do not explain liquidity variations in all the markets that exhibit low sensitivity to external factors. Our results are robust to the use of alternative proxies. The analysis in sub-periods confirms our results showing that most markets are not very sensitive to fluctuations and external shocks of liquidity. For international investors, stock markets in the Middle East and North Africa present an opportunity for further diversification, as these markets exhibit weak correlations between them and with the global market with regard to liquidity.

The performance of logistics service providers and the logistics costs of shippers: a comparative study of Finland and Switzerland

This article analyses the market dynamics between shippers in the manufacturing sector and logistics service providers (LSPs) in Finland and Switzerland, focusing on factors that are characteristic of the demand and supply sides of logistics markets such as performance indicators, financial ratios and relevant macroeconomic indicators. The development of shippers’ logistics costs over a period of ten years is analysed as a proxy for cost savings. This is mirrored against the development of the LSPs’ financial performance. The share of logistics costs in the turnover of Finnish shippers is consistently higher than that of their Swiss peers, whereas Finnish LSPs perform financially better than their Swiss peers. This implies that Finnish and Swiss logistics markets differ in terms of market power and interdependence between shippers and LSPs. The results indicate that the sub-regional interdependence and market power of LSPs, caused by a lack of competition, explain some of the differences in logistics costs.     

The role of complementary products on platform adoption: Evidence from the video console market

This paper studies the importance of the interdependences within platform-based markets. Specifically, the work examines the influence of complementary product portfolios on the adoption of platforms by individuals. The study analyzes data from a panel of 17 video game platforms in three regions (the US, Japan and Europe) for the period between 1989 and 2011. The results suggest that platform adoption is driven by the availability and users of complementary products. The study also finds that this impact is stronger when platform providers jointly manage the in-house complementary product portfolio and the platform. These findings reveal that decisions on complementary products act as strategic drivers of adoption in platform-based markets.     

AN ALGORITHMIC INFORMATION THEORETIC APPROACH TO THE BEHAVIOUR OF FINANCIAL MARKETS

Using frequency distributions of daily closing price time series of several financial market indices, we investigate whether the bias away from an equiprobable sequence distribution found in the data, predicted by algorithmic information theory, may account for some of the deviation of financial markets from log‐normal, and if so for how much of said deviation and over what sequence lengths. We do so by comparing the distributions of binary sequences from actual time series of financial markets and series built up from purely algorithmic means. Our discussion is a starting point for a further investigation of the market as a rule‐based system with an algorithmic component, despite its apparent randomness, and the use of the theory of algorithmic probability with new tools that can be applied to the study of the market price phenomenon. The main discussion is cast in terms of assumptions common to areas of economics in agreement with an algorithmic view of the market.     

Spoils from the Spoiled: Strategies for Entering Stigmatized Markets

Stigmatized markets are those where either the products/services, or the consumers, or both, have been collectively, negatively stereotyped and devalued by one or more stakeholder audiences in ways that discredit the overall market. Many stigmatized markets exist, and many flourish, yet little systematic attention has focused on entry into such markets. Our article addresses this gap by conceptualizing various strategies for entering stigmatized markets. We further present propositions regarding the market‐level factors that can influence which of these strategies firms will choose to employ. The contributions include: conceptually clarifying the nature of stigmatized markets; identifying additional types of entry strategies relevant for entering stigmatized markets; theorizing the conditions under which firms would choose one entry strategy over another; and opening up for consideration the effects that market entry may have on stigmatized actors in targeted markets.     

Drivers of optimal prices in two-sided markets: the state of the art

In two-sided markets, a platform has two groups of customers and enables their interactions. Demand on one market side depends on demand on the other; therefore, when platforms set prices, they must consider this interdependency and set prices on both sides simultaneously. By surveying the vast theoretical marketing and economics literature, this article provides a clear and systematic overview of profit-maximizing pricing in two-sided markets. It identifies and structures the various drivers of those optimal prices. Using this framework, it summarizes the findings from prior research and offers an assessment of the state of the art with regard to drivers of optimal prices and their impacts on a platform’s price setting. This improves understanding of both the principles of two-sided markets and their optimal pricing. Finally, this state of the art paper suggests some directions for further research.     

Credit market constraints and labor market decisions

In this paper, we examine whether imperfections in credit markets spill over to other markets, particularly the labor market. We take the case of Italy, a country that experienced changes in the mortgage market brought about by the 1992 European unification and other institutional shifts. These events make Italy a good laboratory to study the effects of financial markets on the labor market. Using household data from the Bank of Italy between 1989 and 1993, we estimate the relationship between female participation and mortgage use. We find a significant impact of mortgages on women's participation in the labor market.     

Risk spillover and network connectedness analysis of China’s green bond and financial markets: Evidence from financial events of 2015–2020

This study investigated the dynamic return and volatility spillovers, together with the network connectedness analysis between China’s green bond and main financial markets. Based on a multidimensional DCC-GJRGARCH model and the spillover index method, we found significant two-way risk spillovers between the green bond market and traditional bond markets. Moreover, the green bond market was subject to one-way risk spillover from the stock and commodities markets. Meanwhile, risk spillovers between the green bond market, forex market, and monetary market were not significant. Finally, network connectedness analysis provided specific information about connectivity and strength during different subperiods corresponding to financial events. The analysis indicated that under the influence of emergencies, China’s financial market will enhance the risk-spillover level by transforming the same type of market’s internal spillover into cross-market spillover.     

Frontier stock market integration and the global financial crisis

This paper examines the stock market integration between frontier and leading markets, focusing on the periods of pre and post global financial crisis. Using time-series analysis, the results mostly support leading markets can Granger-cause frontier markets. Frontier markets in different regions have distinct relationships with leading markets. Population growth, industry value, interest rate, tax rate, and tariff of the frontier markets significantly influence the integration between both markets. Energy, gross national income, stock traded value, and high-technology exports of leading markets saliently influence the integration. Finally, the global financial crisis impacts the relationship between the frontier and leading markets and changes the determinants of stock market integration.     

Evolving Market Efficiency with an Application to Some Bulgarian Shares

With new technically advanced methods and computers at our disposal, the efficient market hypothesis is once again being debated. At the same time, we are witnessing an unprecedented growth in both existing and new financial markets. These new markets are often in economies which have just recently embraced free market economics; we term these stock markets infant markets. Such stock markets are obviously not efficient in allocating the supply of savings to productive capital. We do not test whether or not these infant markets are informationally efficient, but instead examine whether and how they are becoming more efficient. We propose modelling the excess returns of individual securities using a multi-factor model with time-varying coefficients and generalised auto-regressive conditional heteroskedastic (GARCH) errors. If the markets are becoming more informationally efficient or the agents are learning, we would expect this to manifest itself as the time-varying coefficients becoming more stable as time increases. We test our model using data on four Bulgarian shares. First, we estimate an AR(2) model and a GARCH-M(1,1) model for the shares. Then, we estimated our AR(2) model with time varying coefficients and GARCH type errors. We find varying levels of efficiency and varying speeds of movement towards efficiency within our sample of four shares.

多归属纵向差异化双边市场下竞争均衡

双边市场作为产业组织理论研究的热点问题,涉及平台纵向差异化的研究还很少,本文依照现实中普遍存在的双边的多归属和平台之间差异化的情况,构造了网络外部性参数不对称的多归属差异化Hoteling模型,并考察了新均衡下双边平台的定价、市场势力和利润情况。我们发现,单归属均衡受平台质量差别程度影响,多归属均衡受相异平台质量影响较大;网络外部性参数的不对称是双边市场与单边市场均衡差别的主要原因;其次与单归属均衡结果相比,多归属差异化均衡时拉大了两平台间上下游定价、市场份额和利润差额。     

The importance of consumer multihoming (joint purchases) for market performance: Mergers and entry in media markets

Consumer “multihoming” (watching two TV channels, or buying two news magazines) has surprisingly important effects on market equilibrium and performance in (two‐sided) media markets. We show this by introducing consumer multihoming and advertising finance into the classic circle model of product differentiation. When consumers multihome (attend more than one platform), media platforms can charge only incremental value prices to advertisers. Entry or merger leaves consumer prices unchanged under consumer multihoming, but leaves advertiser prices unchanged under single‐homing: Multihoming flips the side of the market on which platforms compete. In contrast to standard circle results, equilibrium product variety can be insufficient under multihoming.     

The Organization,Operation, and Outcomes of Actually Existing Markets: A Suggested Approach for Empirical Analysis

Public policies have become embedded with market‐based mechanisms to radically transform essential goods and services markets. This article proposes a framework for empirical analysis of these markets. Key theoretical propositions are distilled to 12 distinctive properties of markets. These properties foreshadow a set of questions to interrogate a market's structure, operation, participants, behaviors, rules, and price setting to generate a substantive, realistic picture of outcomes. This “analytical grid” of questions is applied to four Australian essential goods and services markets. The findings unequivocally demonstrate a very different picture of markets from that promulgated by mainstream neoclassical economics and public policies.     

THE ECONOMICS OF COMMUTING AND THE URBAN LABOUR MARKET

ABSTRACT. The spatial distribution of households and firms, or urban spatial structure, is a core element of the study of urban economics and the crucial determinant of commuting patterns. This paper examines developments in the analysis of urban spatial structure and commuting are related to the urban labour market—that is the analysis of labour supply and labour demand in a spatial context. These developments have been overlooked in the traditional approach to urban structure and commuting where most attention has been devoted to the markets for land and housing rather than the market for labour. Yet a little reflection suggests that the labour market might have a great deal to do with the location decisions of households and firms, and hence with commuting patterns. We argue that much criticism of the economic analysis of urban structure and commuting can be addressed by explicit incorporation of the labour market into the conventional model of urban location. This criticism includes findings that the theory cannot explain the tendency for richer households to live farther from the central business district and commute farther to work (Wheaton, 1977) and findings of substantial unexplained or 'wasteful' commuting according to conventional theory (Hamilton, 1982). The paper begins by outlining the basic model of residential location and commuting (Section 2). We then consider extensions that involve the introduction of labour supply decisions and which determine the value of commuting time (Section 3). More recent extensions involve the introduction of decentralized workplaces (Section 4) and, logically, the issues of job search and migration (Section 5). We conclude with a summary of the progress in incorporating labour market behaviour into the analysis of urban structure and commuting and our suggestions for further research in this area.     

Managing competitive software component supplier relationships

This study addresses purchasing challenges faced by companies buying commercial software components. The purpose is to find out how we can understand the purchasing challenges in software component business. First we develop pre-understanding based on knowledge on competitive supplier relationships and competitive bidding. This is elaborated empirically through a qualitative case study. We contribute to prior literature by concluding that the nature of software component supplier relationships is influenced by the object and costs of exchange. We also argue that, in markets like software component business, it is essential to pay attention to the development of the whole supply market.
