During the last years, the growth of transactions made through credit and debit cards has presented quite signif- icant increases both in number and in amounts. This paper studies the existence of economies of scale in the pro- cessing of such transactions, a situation that would exist if it were compatible with the existence of a single firm destined to the processing of said operations. The existence of a single firm for processing is not in itself a problem per se, which does generate problems for the competition is the structure of said firm, because for the period of time analyzed, its shareholder composition was composed of The main banks that issue these cards, but also have given them the function of being the acquirer of the merchants for these payment methods, which generates a vertically inte- grated structure, which creates competition problems in the market. After estimating the model indirectly from a cost function, this work determines the existence of economies of scale in the industry.

From society’s point of view and the exchange of products, metal and gold, till the digital era of cryptocurrencies mediated a lot of phases in payment methods that Greeks used. In this assignment, means of payment are presented and analyzed through the years, differentiations and trends are examined as well as Greek citizens’, and not only, choices are commented according to the means of payment they use via statistical reports conducted by related entities. The aim of this primary research that has been developed in Delta Municipality is the specifying of factors which have an impact on users’ payment choices and also the discovery of a relation probably between those choices and those of sex, age, level of income or level of education. Findings show the general dominations of debit cards in all ages and level of income, for each kind of transaction (natural or digital), confirming the raise of plastic money in Greece after capital controls’ arrival. Speed, directness and convenience are the characteristics which are necessary to be fulfilled by a means of payment, but also another modern reason and necessity of plastic money is the new tax-free builder regime. Furthermore, loyalty programs that cards provide most of the time are really tempting. There is no familiarization neither with cryptocurrencies nor the new contactless media, but only for the concept, independently of age. Finally, grey payments are still a concerning issue, which are preferred by everyone verifying the Greek reality.

As the volume of purchases for products and services on the Internet has increased and the chosen method of payment is a credit or debit card, e-commerce merchants must be capable of accepting such payment methods. Unfortunately, cyber-criminals have found ways to steal personal information found on credit cards and debit cards and fraudulently use this information to purchase products and services which costs merchants lost revenue and fees for chargebacks. This article discusses the process by which credit card payments are processed beginning with the e-commerce merchant’s web site to a credit card processor or service gateway to the credit card company’s network to the issuing bank’s network with an accept or decline response being returned to the merchant’s shopping cart system via the same networks. The article addresses the issue of credit card fraud in terms of how the cyber-criminals function and the potential solutions used to deter these attempts by the cybercriminals. A list of preventive measures that should be used by e-commerce merchants is provided.

Merger dan akuisisi telah menjadi pilihan utama dalam pelaksanaan konsolidasi perbankan yang direkomendasikan dalam rangka penguatan industri perbankan di Indonesia. Proses merger dan konsolidasi ini membutuhkan biaya besar dan mengandung resiko, dua factor yang menyebabkan penurunan tingkat efisiensi bank yang telah melakukan merger.Penelitian ini menunjukkan bahwa proses merger menurunkan efisiensi bank, meski berdampak positif terhadap stabilitas dari efisiensi bank tersebut. Ini menunjukkan manajemen bank yang lebih baik setelah merger dan peningkatan economies of scale. Sebelum merger, bank harus meningkatkan efisiensi terlebih dahulu, misalnya dengan meningkatkan produktivitas tenaga kerja dan peningkatan utilisasi teknologi. Paper ini menunjukkan, jika skor DFA 0,7, bank dapat meraih keuntungan economies of scale, economies of scope dan technical progress yang dapat meningkatkan efisiensi.Beberapa rekomendasi yang diusulkan, pertama, Bank Indonesia seharusnya mengarahkan manajemen perbankan dalam hal pengalokasian biaya operasional secara optimal. Kedua, harus ada upaya untuk mengembalikan tingkat efisiensi bank pada level efisiensi semula. Ketiga, Bank Indonesia, harus mengarahkan perbankan untuk mengabsorpsi teknologi sejauh mungkin. Keempat, efisiensi internal merupakan aspek penting yang harus diraih sebelum proses merger dilakukan.JEL: C29, C39, D23, G21Keywords : X-efficiency, Merger, Seemingly Unrelated Regression, Cost function, Economies of scale, Bank.

Abstract Today’s highly competitive, global marketplace is redefining the way companies do business. Many companies are being faced with the challenge of providing as much variety as possible for the market with as little variety as possible between products in order to maintain economies of scale while satisfying a wide range of customer requirements. Developing a family of products — a group of related products derived from a common product platform — provides an efficient and effective means to realize sufficient product variety to satisfy a range of customer demands. In this paper the Product Platform Concept Exploration Method (PPCEM) is presented, providing a Method that facilitates the synthesis and Exploration of a common Product Platform Concept that can be scaled into an appropriate family of products. As an example, the PPCEM is employed to design a family of universal electric motors that are also compared against a benchmark group of individually designed motors. The focus in this paper, however, is on the PPCEM and not on the results, per se.

The Impact

SummaryUsing a unique data set on German child care centers, we estimate a long-run multi-product cost function for child care provision in Germanywhile taking into account legal minimal labor input restrictions. For a representative child care center we find economies of scale, a U-shaped average cost curve, and indications of diseconomies of scope. The legally stipulated minimum child-to-staff ratio is manifested in a positive Lagrange multiplier, showing that modeling legal restrictions is necessary to avoid misspecification error. Our study provides a useful tool for policymakers in estimating the effects of future demographic change on child care costs.
