Opis:
Forecasting process efficiency depends – to a large extent – on the correct determination of the forecasted variable. Therefore, companies should use for sales forecasting, the variables that reflect actual consumer demand. However in practice, since demand is usually not directly observable, many operational measures of demand are used. In the manufacturing and retail enterprises, the most often used variables are historical orders, shipments, and billed sales volumes. The purpose of this paper is to characterise the effects of using as the predicted variable, different operational measures of consumer demand. Theoretical discussion is illustrated by an attempt to estimate errors in demand forecasts for Avon Cosmetics’ products that are related to changes in data used for forecasting.

Opis:
Demand forecasts in a business may be constructed by various methods, e.g. by using Type-I formal models, or by using type-II formal models based on experts’ opinions. The experts can be the business’s managers or persons from outside of the studied business. The experts can not only construct forecasts, but also subjectively specify the probability of them coming true. In this article, the Weibull distribution is described, a distribution that may be applied in the process of constructing product demand forecasts for a business. The methodology for constructing a point forecast is explained, along with the methods for evaluating the chances of the forecast coming true and the methods for judging the probability connected with sales profitability.

W artykule przedstawiono tło gospodarcze zaniku obsługi pasażerskiej koleją niektórych miast powiatowych na przełomie lat 90-tych ubiegłego stulecia i pierwszej dekady XXI wieku, oraz szanse i możliwości na ponowne ich włączenie w sieć przewozów kolejowych. W związku z procesem realizacji dokumentacji przedprojektowych dla programu „Kolej Plus” obejmującego przywracanie połączeń pasażerskich, omówiono problematykę prognozowania potencjału popytowego w transporcie kolejowym. Przedstawiono prostą metodę szacowania potencjału dla miejscowości, które nigdy takiego połączenia nie miały, bądź utraciły je w wyniku likwidacji linii lokalnych.
The article presents the economic background of the closure of passenger service by rail in some county towns at the turn of the 1990s and the first decade of the 21st century, and the chances and opportunities for their reintroduction into the rail transport network. In connection with the process of realisation of pre-project documentation for the Kolej Plus programme including the restoration of passenger connections, the problem of forecasting the demand potential in railway transport was discussed. A simple method of estimating the potential was presented for towns, which have never had such a connection or have lost it as a result of liquidation of local lines.

Opis:
Public transportation provides its services to both urban centers and neighboring areas in the immediate vicinity of the city. The problem of urban transportation is evident, the number of people willing to use public transportation has decreased. Therefore, there is a need to delve into the issue and conduct an analysis of the demand for urban transportation in Poland in 2000-2030, this will allow us to assess in what direction urban transportation is heading, whether there is an increase in the number of people using it, or whether there is a downward trend (Zielińska 2018). Based on CSO statistics from 2009-2020 for the analysis of demand for public transportation in Poland, a forecast of people using public transportation was conducted using Statistica software for 2021-2030. Due to the situation with the COVID-19 pandemic, the study was conducted in 2 ways – with and without 2020. Public transportation will make less and less profit and even losses for the next few years through rising gasoline and energy prices. Virtually in each of the provinces, and likewise throughout Poland, a decline in the number of people willing to use public transportation is evident. conclusions. On the basis of the surveys carried out, there is a general trend that shows the current state of public transport. In most of the cases studied, a similar conclusion emerges, namely that public transport will experience a marked decline in the coming years. The number of people who want to use public transport will decrease, mainly due to the COVID-19 pandemic and people’s fears for their own safety.

Opis:
The article discusses housing demand. We focus on disequilibrium of a urban housing market and location derived segmentation. Based on literature review, we identify reasons behind housing mobility and housing location choice at household level. In the second part of the article we focus on the interaction between housing demand of urban development patterns (especially spatial aspects of it). The main objective of this paper is to show the relationship between two major dimensions of individual housing demand: (i) mobility choice and (ii) location choice and spatial transformations within the metropolitan area. The article is a critical analysis of the literature. We attempt to identify the main factors affecting the demand for housing in a specific metropolitan area. Previous studies point to a number of factors affecting the residential mobility of households. The most important are: the life cycle, relative deprivation, social capital, gender and economic situation. Studies show that these factors are correlated and are subject to mutual interactions. Reflections on diversity and segmentation of metropolitan housing markets lead to the conclusion that the local housing market can be seen as a nested structure. Each metropolitan housing market is divided into submarkets − based on location and housing services quality. The housing search is therefore sequential and hierarchical in nature. Among the most important factors determining the household choice of location within the local housing market are: economic capital, social status, spatial relationships, lifestyle, racial segregation and the quality of schools. The synthesis of the results leads to the conclusion that the demand for housing is related to certain spatial phenomena occurring in metropolitan areas. We highlight four aspects in particular:– – communication system (mass transit, road system, parking in the city center), – spatial order, – access to schools and public services (excessive density of housing and inadequate social infrastructure), – urban sprawl. Due to the information asymmetry and inelastic supply in housing market subsegments it can cause persistent imbalances and emergence of deprived areas within the urban structure.

Opis:
The aim of the article is to assess changes in the enterprises’ demand for financial insurance. The analysis covered expenses incurred by business entities on purchase thereof and supply by the entity. Data used in the study came from secondary sources published in studies by the Polish Financial Supervision Authority (KNF), the Polish Chamber of Insurance (PIU) and the Central Statistical Office (GUS). Furthermore, information from the studies-related literature has been included. The time period of studies covered the years 2005–2018. Selected types of insurance included in financial insurance have been presented herein and industries which these products are especially targeted at have been indicated. Moreover, supply by entities has been discussed with an indication of insurers who hold a leading position in the financial insurance sales in Poland. It has been stated that the demand (by value) for financial insurance in the years 2005–2018 was growing. The amount of the gross premium written in 2018 was twice as high as in 2005 and amounted to PLN 1.09 billion. Furthermore, it has been determined that the highest average dynamics of market growth concerned insurance from various financial risks (group 16), which are usually offered jointly with other insurance products, but also the dynamics of expenses incurred on purchasing surety was over 200%, whereas, in 2018 it was even 360%.

Will be considered transport company exploiting the uniform in the sense of destination, means of transport such as tankers, with a total transport potential equal to a loading units (e.g. tones). The company operates in the transport market, where demand for transport services is random. The problem of fitting the transport potential of a transport company to the demand for such services is formulated. As measure of this fit assumes that the probability of a firm's transport potential is not being exceeded by demand over the given time horizon. Practically useful formulas for estimating such probability for cases where demand for transport services is described by stationary and non-stationary normal stochastic processes. The results are illustrated by numerical examples.

Industry 4.0 will affect the complexity of supply chain networks. It will be necessary to adapt more and more to the customer and respond within a time interval that is willing to accept the product waiting. From these considerations, there is a need for a different way of managing the supply chain. The traditional concept of supply chain as a linear system, which allows optimizing individual subsystems, thus obtaining an optimized supply chain, is not enough. The article deals with the issue of supply chain management reflecting demand behaviour using the methodology Demand Driven MRP system. The aim of the publication is to extend the knowledge base in the area of demand-driven supply logistics in the context of Industry 4.0 and verify the processed theoretical knowledge in a case study.

This article presents the results of empirical research on the labour market of city travel guides, regional guides and mountain guides as well as tour leaders. The aim of this article is to evaluate the demand for the services of travel guides and tour leaders. The study included tourism entrepreneurs and the method of a diagnostic survey with the use of computer-assisted telephone interviewing (CATI) was applied. The obtained results confirmed the thesis that the labour market of travel guides and tour leaders is not stable and this is due to the seasonality, level of earnings and changing model of travel organization. The study also showed that in the five-year period from the deregulation of the professions, the market relations between travel guides and tour leaders on the one hand and tourism entrepreneurs on the other did not undergo fundamental changes. The results of the study may be useful for tour operators, organisations associating travel guides and tour leaders as well as for tourism administration at the central and regional level.

Opis:
The author analyzes the demand for shares and attempts to determine its influence on the liquidity of the Warsaw Stock Exchange. The analysis was conducted by calculating and bringing together values of key importance to the liquidity of the market and investment activity on the Polish stock market. The analysis showed that the liquidity of the Polish stock market decreased in the analyzed period (1995-2005). First, there was a drop in the value of stock trades in relation to the market’s capitalization. Subsequently, there was a problem involving the substantial concentration of trade on the exchange. On the basis of this situation, attempts were made to check the demand side of the stock market, especially in the institutional investor segment. Analyses conducted by the author indicate that, as a result of a dynamic increase in pension and investment fund assets in 2000-2005, these institutions substantially increased the value of shares in their possession, withdrawing some of the stock from “active” turnover. Over the next few years, more than 40% of the assets invested by these institutions in stock were tied up in the portfolios of open-ended pension funds. However, in the years that followed, assets held by institutional investors were subject to decreased turnover. This seems to indicate that institutional investors could pose a threat to the market’s liquidity by channeling substantial assets to the domestic stock market in a situation in which the supply of shares was insufficient. However, a supplementary examination of the average turnover in WSE-listed shares, particularly those making up the market’s free float, revealed that the activity of institutional investors, though decreasing with each passing year, was several times higher than average investment activity on the stock market. In other words, transactions made by institutional investors were the key driving force behind the market’s liquidity in the analyzed period. Unfortunately, the positive influence of institutional investors decreased in 2003-2005, a period that saw a major increase in pension and investment fund assets. The insufficient-and continually decreasing-liquidity of the stock market, coupled with the dynamic development of the institutional investor segment, particularly pension funds, justifies worries over the liquidity and stable development of the Polish stock market.

Opis:
In this work the identification of the process of changes in rural tourism has been presented. The evolution of rural tourism is defined by changes occurring in the countryside and in tourism itself. The presented analysis of the evolution of rural tourism is based on a change in the approach to the definition of rural tourism, to the supply and demand, and to the influence of rural tourism on rural environment. The analysis is restricted by the available literature of the subject and by statistical data for Poland. In the beginning the rural tourism was considered as the tourism occurring in the countryside. Afterwards, many aspects of rural tourism were recognized, which is reflected by its definitions. The evolution of tourism supply also took place and, as a result, the tourism supply became more diverse. Apart from traditional forms of vacational tourism, some new forms requiring a specifically designed landscape, equipment, cultural events, managment etc. appeared. New clients looking for specific experiences in rural tourism also appeared. For such clients the countryside became a tourism product. They are also able to provide a sufficient income for the sustainable development of the countryside. Providing tourism services by farms often leads to the collapse of their agricultural activity, and, in consequence, to the dominating role of tourists’ service, which leads to the multifunctionality of the countryside. Such a hypothesis requires further empirical investigations. The literature of the subject indicates that the model of tourist area lifecycle (TALC), as proposed by Butler in 1980, is useful for carrying out analyses of rural tourism evolution.
