Optimal contracts for vertically connected, unionized duopolies

Grandner, Thomas January 2000 (has links) (PDF)
In this paper a vertically structured duopolistic market with unionized price setting firms is analyzed. The form of the contract of the transactions between upstream and downstream firms can be linear pricing, franchising or vertical integration. It is known from literature (Irmen 1997) that the price elasticity of the industry demand and the degree of product differentiation are the decisive factors in the determination of the profit maximizing form of the contract. In this paper it is shown that the bargaining power of the union is an additional factor. With a higher bargaining power linear pricing becomes less preferable.

A note on franchising and wage bargaining

Grandner, Thomas January 2004 (has links) (PDF)
A franchise contract relocates distributable rent between franchisor and franchisee. With decentralized wage bargaining this modifies the position of the union in wage bargaining. If the rent is relocated to the franchisor completely, then even a strong union is not able to raise the wage above reservation level in the franchisee's firm. If franchisor and franchisee negotiate on rent division, there is an incentive to increase franchise fee with the consequence that franchisee's wage is pushed down. Therefore the overall rent assigned to labor depends on the differences of labor intensity in the franchisor's and franchisee's firm. Firm owners may be able to transfer distributable rents from a firm with a strong union to one with a weak union. Additional a franchising contract shows up a first mover advantage. The franchising contract is placed before wage bargaining, benefiting the franchisor.

A note on unionized firms' incentive to integrate vertically

Grandner, Thomas January 2000 (has links) (PDF)
In this paper I analyze a vertically structured monopolized market with unionized firms. I compare two types of contracts: vertical integration and franchising. With franchising and wage bargaining at the firm level the union in the downstream firm is either very powerful or has no bargaining power at all, depending on the specific time structure of the model. These arguments could make integration preferable for the profit owners even if integration is accompanied by small transaction costs.

Investment under Uncertainty in Electricity Generation

Gugler, Klaus, Haxhimusa, Adhurim, Liebensteiner, Mario, Schindler, Nora 09 1900 (has links) (PDF)
The recent transformation of European electricity markets with increasing generation from intermittent renewables brings about many challenges. Among them, decaying wholesale prices, partly due to support schemes for renewables, may send insufficient investment signals for other technologies. We investigate the investment decision in a structural equation based on the Tobin's q-model, which we extend by both industry- and firm-technology-specific uncertainty. We utilize rich and novel data at the disaggregated firm generation technology level of European electricity generating firms for the period 2006-2014. Our results show that investment in any generation technology follows market incentives despite sunk and irreversible capital, confirming the implications of the q-model. Moreover, while firm-technology-specific uncertainty decreases firms' investment activity, especially in coal and gas, aggregate uncertainty triggers firms' investment. Our results raise concerns about system reliability in the long run since conventional technologies still serve as a flexible system back-up.

A Temperature-Sensitive Mutant of Escherichia Coli With an Alteration in Ribosomal Protein L22

Burnette-Vick, Bonnie, Champney, W. Scott, Musich, Phillip R. 01 February 1994 (has links)
A temperature-sensitive, protein synthesis-defective mutant of Escherichia coli exhibiting an altered ribosomal protein L22 has been investigated. The temperature-sensitive mutation was mapped to the rplV gene for protein L22. The genes from the wild type and mutant strains were amplified by the polymerase chain reaction and the products were sequenced. A cytosine to thymine transition at position 22 of the coding sequence was found in the mutant DNA, predicting an arginine to cysteine alteration in the protein. A single cysteine residue was found in the isolated mutant protein. This amino acid change accounts for the altered mobility of the mutant protein in two-dimensional gels and during reversed-phase HPLC. The temperature-sensitive phenotype was fully complemented by a plasmid carrying the wild type L22 gene. Ribosomes from the complemented cells showed only wild type protein L22 by two dimensional gel analysis and were as heat-resistant as control ribosomes in a translation assay. The point mutation in the L22 gene is uniquely responsible for the temperature-sensitivity of this strain.

Market Structure and Competition in Transition: Results from a Spatial Analysis

Lábaj, Martin, Morvay, Karol, Silanic, Peter, Weiss, Christoph, Yontcheva, Biliana 02 1900 (has links) (PDF)
The present paper provides first microlevel (indirect) empirical evidence on changes in the determinants of firm profitability, the role of fixed and sunk costs, as well as the nature of competition for a transition economy. We estimate size thresholds required to support different numbers of firms for four retail and professional service industries in a large number of geographic markets in Slovakia. The three time periods in the analysis (1995, 2001 and 2010) characterize different stages of the transition process. Specific emphasis is given to spatial spill-over effects between local markets. Estimation results obtained from a spatial ordered probit model suggest that entry barriers have declined considerably (except for restaurants) and the intensity of competition has increased. We further find that demand spill-overs and/or the effects associated with a positive correlation in unobservable explanatory variables seem to outweigh negative spill-over effects caused by competitive forces between neighboring cities and villages. The importance of these spatial spill-over effects differs across industries. / Series: Department of Economics Working Paper Series

Productivity Growth and the General X-factor in Austria´s Gas Distribution

Gugler, Klaus, Liebensteiner, Mario 10 1900 (has links) (PDF)
We estimate cost functions to derive productivity growth using a unique database on costs and outputs of essentially all regulated Austrian gas distribution companies over the period 2002-2013, covering the times before and after the introduction of incentive regulation in 2008. We estimate a concave relation between total costs and time, and a significant one-off but permanent reduction in real costs after an imposed reduction in granted costs in the course of the introduction of incentive regulation. Our results imply that technological opportunities were higher in the early years of the sample than in later years, and that productivity growth grinded to a halt from 2008 on. We conclude that technological opportunities are exhausted (for the time being) in the Austrian gas distribution sector giving rise to an optimal general X factor (X-gen) of zero for the foreseeable future.

Static or Dynamic Efficiency: Horizontal Merger Effects in the Wireless Telecommunications Industry

Grajek, M., Gugler, Klaus, Kretschmer, T., Miscisin, I. January 2019 (has links) (PDF)
This paper studies five mergers in the European wireless telecommunication industry and analyzes their impact on prices and capital expenditures of both merging carriers and their rivals. We find substantial heterogeneity in the relationship between increases in concentration and carriers' prices. The specifics of each merger case clearly matter. Moreover, we find a positive correlation between the price and the investment effect; when the prices after a merger increase (decrease), the investments increase (decrease) too. Thus, we document a trade-off between static and dynamic efficiency of mergers.

Market structure and competition in the healthcare industry. Results from a transition economy

Lábaj, Martin, Silanic, Peter, Weiss, Christoph, Yontcheva, Biliana January 2018 (has links) (PDF)
The present paper provides first empirical evidence on the relationship between market size and the number of firms in the healthcare industry for a transition economy. We estimate market-size thresholds required to support different numbers of suppliers (firms) for three occupations in the healthcare industry in a large number of distinct geographic markets in Slovakia, taking into account the spatial interaction between local markets. The empirical analysis is carried out for three time periods (1995, 2001 and 2010) which characterise different stages of the transition process. Our results suggest that the relationship between market size and the number of firms differs both across industries and across periods. In particular, we find that pharmacies, as the only completely liberalised market in our dataset, experience the largest change in competitive behaviour during the transition process. Furthermore, we find evidence for correlation in entry decisions across administrative borders, suggesting that future market analysis should aim to capture these regional effects.

Dependent Forms of Self-employment in the UK. Identifying Workers on the Border between Employment and Self-Employment.

Böheim, Rene, Muehlberger, Ulrike January 2006 (has links) (PDF)
We analyse the characteristics of workers who provide work on the basis of a civil or commercial contract, but who are dependent on or integrated into the firm for which they work. We argue that these dependent self-employed lose their rights under labour law, receive less favourable benefits from social security protection and are often beyond trade union representation and collective bargaining. Using data from the British Labour Force Survey we test two hypotheses: (1) Dependent self-employed workers are significantly different from both employees and (independent) self-employed individuals, thus forming a distinct group. (2) Dependent selfemployed workers have lower labour market skills, less labour market attachment and, thus, less autonomy than self-employed workers. The data support our hypothesis that dependent selfemployed workers are a distinct labour market group which differs from both employees and independent self-employed individuals. Men, older workers, those with low education and a low job tenure have greater odds of working in dependent self-employment than their counterparts. Our results suggest that dependent forms of self-employment are used by firms to increase labour flexibility. (author's abstract) / Series: Department of Economics Working Paper Series
