This paper summarizes the experiences to date of the new EU countries (the Czech Republic, Estonia, Hungary, Latvia, Lithuania, Poland, Slovakia, and Slovenia—the EU8) in the reform of higher education systems in a period of growing demand; changing patterns of access; rapid expansion and increased participation rates; and an apparent dilution of average quality. The study discusses the growing experience with a variety of financing mechanisms in EU8 countries, drawing on detailed country case studies, and seeks to develop some useful lessons from experience, mindful that each country will continue to develop its own solution based on national priorities.

This paper analyzes the impact of the policy of replacing environmental protection “fees” with “taxes” on enterprise green innovation based on the Chinese A-share listed companies sample from 2015 to 2019. This paper tries to analyze the factors that may affect the level of green innovation of enterprises and the ability of enterprise green innovation (GI) under the background of the implementation of this policy. This paper adopts the difference-in-differences method (DID), takes 1 January 2018 as the time variable demarcation boundary and uses the heavily polluting industry as the dummy variable boundary, conducts group research on the experimental variables, and observes and analyzes the impact of heavily polluting industries and non-heavy pollution before and after the implementation of the policy. It is found that the policy significantly improves green innovation and the R&D efficiency of green innovation of enterprises in heavy pollution industries. Further research reveals that after the implementation of the policy, large enterprises and private enterprises, compared with SMEs and state-owned enterprises, lay more stress on improving green innovation technology. In the end, it examines the relationship between senior executives’ academic research experience and enterprises’ green innovation and finds that senior executives’ academic research experience can not only promote green innovation, but also improve the R&D efficiency of green innovation. The research results of this paper provide a theoretical basis for decision makers and enterprise management in formulating rules and managing enterprises.

The house cricket, Acheta domesticus L. (Orthoptera: Gryllidae) is one of the most important species of industrialized insects in the United States. Within the past five years the market of cricket powder as a food ingredient has been growing with increasing consumer interest on more sustainable sources of food. However, high labor costs of cricket production and high prices of cricket feed formulations result in cricket powder market prices much higher than other protein-rich food ingredients, making cricket powder only competitive within the novelty food market. In this study new diets formulated using by-products were developed using dietary self-selection followed by regression analysis. Crickets selected among seven different combinations of ingredients. Consumption ratios of food ingredients and by-products were used to determine macro and micro-nutrient intake. Regression analysis was used to determine the individual nutrient intake effect on cricket biomass production. Intake of vitamin C, sterol, manganese, and vitamins B1 and B5 had the most significant impact on live biomass production. Four diets were formulated based on this information and compared with a reference (Patton's 13) and a commercial diet. Although, crickets reared on Patton's diet 13 produced the most dry-weight biomass and developed the fastest, diet 4 (consisting of 92% by-products) generated the most profit (with a cost of $0.39 USD per kg) after an economic analysis that did not include the commercial formulation. Dry-weight biomass production was not significantly different among the four new diets and the commercial diet. This study demonstrated the value of dietary self-selection studies in developing oligidic insect diets and in studies of insect nutrition. This is the first such study involving farmed edible crickets and agricultural by-products. Four new cricket diet formulations contain between 62 and 92% agricultural by-products are included.

This paper investigates the impact of e-waste regulation on new product introduction in a stylized model of the electronics industry. Manufacturers choose the development time and expenditure for each new version of a durable product, which together determine its quality. Consumers purchase the new product and dispose of the last-generation product, which becomes e-waste. The price of a new product strictly increases with its quality and consumers' rational expectation about the time until the next new product will be introduced. \"Fee-upon-sale\" types of e-waste regulation cause manufacturers to increase their equilibrium development time and expenditure, and thus the incremental quality for each new product. As new products are introduced (and disposed of) less frequently, the quantity of e-waste decreases and, even excluding the environmental benefits, social welfare may increase. Consumers pay a higher price for each new product because they anticipate using it for longer, which increases manufacturers' profits. Unfortunately, existing \"fee-upon-sale\" types of e-waste regulation fail to motivate manufacturers to design for recyclability. In contrast, \"fee-upon-disposal\" types of e-waste regulation such as individual extended producer responsibility motivate design for recyclability but, in competitive product categories, fail to reduce the frequency of new product introduction.

This paper focuses on the pricing aspect of the “net neutrality” debate—in particular, the de facto ban on fees levied by Internet service providers on content providers to reach users. This “zero-price” rule may prove desirable for several reasons. Using a two-sided market analysis, we suggest that it subsidizes creativity and innovation in new content creation—goals shared by copyright and patent laws. The rule also helps to solve a coordination problem: since Internet service providers do not completely internalize the effects of their own pricing decisions, lack of regulation may lead to even higher fees charged by all. Finally, allowing for such fees runs the risk of creating horizontally differentiated Internet service providers with different libraries of accessible content, thereby foreclosing consumers and leading to Internet fragmentation.

The last decade has seen a strident public debate about the principle of “net neutrality.” The economic literature has focused on two definitions of net neutrality. The most basic definition of net neutrality is to prohibit payments from content providers to internet service providers; this situation we refer to as a one-sided pricing model, in contrast with a two-sided pricing model in which such payments are permitted. Net neutrality may also be defined as prohibiting prioritization of traffic, with or without compensation. The research program then is to explore how a net neutrality rule would alter the distribution of rents and the efficiency of outcomes. After describing the features of the modern internet and introducing the key players, (internet service providers, content providers, and customers), we summarize insights from some models of the treatment of internet traffic, framing issues in terms of the positive economic factors at work. Our survey provides little support for the bold and simplistic claims of the most vociferous supporters and detractors of net neutrality. The economic consequences of such policies depend crucially on the precise policy choice and how it is implemented. The consequences further depend on how long-run economic trade-offs play out; for some of them, there is relevant experience in other industries to draw upon, but for others there is no experience and no consensus forecast.

This paper explains why payment card networks charge fees that are proportional to the transaction values instead of charging fixed per-transaction fees. We show that, when card networks and merchants both have market power, card networks earn higher profits by charging proportional fees. It is also shown that competition among merchants reduces card networks' gains from using proportional fees relative to fixed per-transaction fees. Merchants are found to earn lower profits under proportional fees, whereas consumer utility and social welfare are higher. Our welfare results are then evaluated with respect to the current regulatory policy debates. (JEL E42, G21, G28)

The status quo of prohibiting broadband service providers from charging websites for preferential access to their customers-the bedrock principle of net neutrality (NN)-is under fierce debate. We develop a game-theoretic model to address two critical issues of NN: (1) Who are gainers and losers of abandoning NN? (2) Will broadband service providers have greater incentive to expand their capacity without NN? We find that if the principle of NN is abolished, the broadband service provider stands to gain from the arrangement, as a result of extracting the preferential access fees from content providers. Content providers are thus left worse off, mirroring the stances of the two sides in the debate. Depending on parameter values in our framework, consumer surplus either does not change or is higher in the short run. When compared to the baseline case under NN, social welfare in the short run increases if one content provider pays for preferential treatment but remains unchanged if both content providers pay. Finally, we find that the incentive to expand infrastructure capacity for the broadband service provider and its optimal capacity choice under NN are higher than those under the no-net-neutrality (NNN) regime, except in some specific cases. Under NN, the broadband service provider always invests in broadband infrastructure at the socially optimal level but either under- or overinvests in infrastructure capacity in the absence of NN.

Product lines are ubiquitous. For example, Marriott International manages high-end ultra-luxury hotels (e.g., Ritz-Carlton) and low-end economy hotels (e.g., Fairfield Inn). Firms often bundle core products with ancillary services (or add-ons). Interestingly, empirical observations reveal that industries with ostensibly similar characteristics (e.g., customer types, costs, competition, distribution channels, etc.) employ different bundling strategies. For example, airlines bundle high-end first class with ancillary services (e.g., breakfast, entertainment) while hotel chains bundle ancillary services (e.g., breakfast, entertainment) at the low-end. We observe, unlike hotel lines that are highly differentiated at different geographic locations, airlines suffer low core differentiation because all passengers (first-class and economy) are at the same location (i.e., same plane, weather, delays, cancellations, etc.). In general, we find product lines with low core differentiation (e.g., airlines, amusement parks) routinely bundle high-end while product lines with highly differentiated cores (e.g., hotels, restaurants) routinely bundle low-end. High-end bundling makes the high-end more attractive, increasing line differentiation (less intraline competition) while low-end bundling decreases line differentiation. Therefore, bundling allows optimal differentiation given a differentiation constraint (complex costs). Last, firms may use strategic bundling for targeting in their core products; e.g., low-end hotels bundle targeted add-ons unattractive to high-end consumers such as lower-quality breakfasts and slower Internet.
