The Private Impact of Public Data: Landsat Satellite Maps Increased Gold Discoveries and Encouraged Entry

How does public data shape the relative performance of incumbents and entrants in the private sector? Using a simple theoretical framework, I argue that public data reduces investment uncertainty, facilitates the discovery of new market opportunities, and increases the relative market share of new entrants relative to incumbents. I shed light on these predictions by estimating the impact of public data from Landsat, a U.S. National Aeronautics and Space Administration satellite mapping program, on the discovery rates of new deposits by incumbents (seniors) and entrants (juniors) in the gold exploration industry. I exploit idiosyncratic timing variation and cloud cover in Landsat coverage across regions to identify the causal effect of public data on the patterns of gold discovery. I find that Landsat data nearly doubled the rate of significant gold discoveries after a region was mapped and increased the market share of new entrants from about 10% to 25%. Public data seem to play an important, yet relatively underexplored, role in driving performance differences across firms. This paper was accepted by Ashish Arora, entrepreneurship and innovation.

Cabeças: disseminação, desigualdade e concentração no mercado de cativos (Luanda, c. 1798-1804)

Based on baptismal parish records, this paper analyses the relative market share between slave traders in Luanda from 1798 to 1804. In the context of high Atlantic demand for slaves, the baptism of cabeças (term used to refer to adult slaves destined for sale) show that the market was at the same time open and concentrated. Alongside many small-scale merchants, that sold a few slaves at a time, an extremely reduced number of large-scale traders dominated the trade in people. However, this select group of nearly monopolistic traders was heterogeneous, since it was composed of different kinds of people, including vessel captains, members of the Luanda elite and men from other parts of the Portuguese monarchy (Brazil and Portugal). The conclusion reached is that the intense participation of different social groups in the business meant that the market for captives had wide political, moral and social support.

Analysis Of The Influence Of Corporate Size, Leverage , Price Earning Ratio (PER) And Return On Equity (ROE) On Company Value

This study aimed to n use values the company can be determined by many factors, among which the size of the company, leverage, the price earnings ratio (PER) and Return On Equity (ROE) Firm size is considered able to influence the value of the company . the large size of the company shows that the company is developing so that investors will respond positively and the value of the company will increase. The relative market share shows the company's competitiveness is higher than its main competitors. Investors will respond positively so that the value of the company will increase. Companies that have total assets with large amounts or commonly referred to as large companies will get more attention from investors, creditors and other users of financial information compared to small companies. If the company has a large total assets, the management will be more flexible in using existing assets in the company. This ease in controlling assets will increase the value of the company. In the face of economic turmoil, usually a more sturdy company stands are large, although it does not rule out bankruptcy, so investors tend to like large-sized companies rather than small-sized companies.

Strategic Positioning of Turkey Agricultural Products on the Agricultural World Market

Applying a strategic management perspective, particularly the BCG tool, this chapter demonstrates that the agricultural products exported by Turkey are distributed unevenly on the four cells of the global agricultural markets matrix: almost of its products (236 products or 85.20% of its portfolio) are Question Marks, two products are a Star, one product is a Cash cow, and 38 products are Dogs. Such a situation creates important strategic choices for the leaders of the country and for its businesses. None of Turkey top ten exports were among the top ten growers in the world. Turkey is world export leader in ten products, but these products are not the world most growing markets, and the country should increase its relative market share in some of its ten top exports, and also consider developing organic product segments, and eliminate tobacco products in its portfolio.

Evaluation of the volume-value relationship in hip fracture care using evidence-based thresholds

Background: Studies have shown high-volume surgeons and hospitals deliver higher value care. The aims of this study were to establish meaningful thresholds defining high-volume surgeons and hospitals performing hip fracture surgery and to examine the relative market share of hip fracture cases using these surgeon and hospital strata. Methods: We performed a retrospective cohort study in a database of 103,935 patients undergoing hip fracture repair. We generated stratum-specific likelihood ratio (SSLR) models of a receiver operating characteristic (ROC) curve using length of stay (LOS) and cost value metrics. Volume thresholds predictive of decreased LOS and costs for surgeons and hospitals were identified. Results: Analysis of annual surgeon hip fracture volume produced two volume categories for LOS and cost: 0–30 (low) and 31+ (high). Analysis of LOS by annual hospital hip fracture volume produced strata at: 0–59 (low), 60–146 (medium), and 147 or more (high). Analysis of cost by annual hospital volume produced strata at: 0–125 (low) and 126+ (high). LOS and cost both decreased significantly ( p < 0.05) in progressively higher volume categories. Low-volume surgeons performed the majority of hip fracture cases, although they were performed at medium- or high-volume centres. Conclusions: This study demonstrates a direct relationship between volume and value, translating to improvement in hip fracture care delivery for both surgeons and hospitals. Higher volume hospitals while lower volume surgeons perform the majority of hip fracture cases, suggesting optimisation opportunities. However, systems-based practices at the hospital level likely drive value to a greater extent than individual surgeons.

COMPETITION FACTORS IN THE MOBILE COMMUNICATION MARKET

One of the most important areas of study of the features of an enterprise's economic activity, especially in conditions when the market is constantly evolving and changing, is the analysis of the enterprise's competitiveness. The importance of research on this topic is that a high level of competitiveness of the company is a guarantee of high profits. In today's conditions, competition is a determining factor in price ordering, an incentive for innovative processes (the introduction of new inventions and technologies into production). It contributes to the crowding out of production of inefficient enterprises, the rational use of resources. Therefore, a constant competitiveness study is necessary both for the enterprise (in order to improve and maintain its position) and for the state (to control the relevant industry). The purpose of this article is a practical study of the competitiveness of Kyivstar JSC in the mobile communications market, namely, the identification of the competitive advantages of the company and the formation of the general condition of this market on the basis of a study of the activities of leaders providing mobile communications services in Ukraine. To cover the situation on the market of mobile operators, in addition to Kyivstar, we briefly analyze the activities of the main competitors of MTS (Vodafone) and Lifecell. The article explores the competitiveness of Kyivstar JSC, considers the main methods for researching competitiveness, defines indicators of market share, relative market share, Herfindahl-Hirschman Index, and builds a competitiveness polygon. An analytical study of Kyivstar’s competitiveness in the mobile services market in Ukraine revealed the existence of a number of problems. The Kyivstar company itself is actively engaged in economic activities and every year increases the number of its customers by positioning itself as a leading mobile operator with the best coverage throughout Ukraine.
