Scenario Planning and Evaluation of Pricing Strategies in the Portuguese Bulk LPG Market

Portugal has the largest LPG (Liquefied Petroleum Gas) share of primary energy demand in the EU (about 5%). Due to the increasing international cost of LPG in the last years and the high price sensitivity of the consumers the preference for substitute energy sources in new and existing consumers has been increasing. To select the kind of energy, some consumer estimate and compare the total costs while others follow agents (equipment sellers) recommendations. It takes time to build agents perception about the most advantageous source of energy, which is seen as an important resource that drives client resource accumulation and retention. Marketing strategies have to take into consideration some market dynamic effects derived from the accumulation and depletion of these resources. A simple system dynamics model was built, combined with Economic Value Added framework, to evaluate some pricing strategies under different scenarios of LPG international cost.

Short-term Value for the Water Stored in Headsensitivity Power System Reservoirs

As it is well known, competitive electricity markets require new computing tools for generation companies to enhance the management of its resources. The economic value of the water stored in a power system reservoir is crucial information for enhancing the management of the reservoirs. This paper proposes a practical deterministic approach for computing the short-term economic value of the water stored in a power system reservoir, emphasizing the need to considerer water stored as a scarce resource with a short-term economic value. The paper addresses a problem concerning reservoirs with small storage capacities, i.e., the reservoirs considered as head-sensitivity. More precisely, the respective hydro plant is head-dependent and a pure linear approach is unable to capture such consideration. The paper presents a case study supported by the proposed practical deterministic approach and applied on a real multi-reservoir power system with three cascaded reservoirs, considering as input data forecasts for the electric energy price and for the natural inflow into the reservoirs over the schedule time horizon. The paper presents various water schedules due to different final stored water volume conditions on the reservoirs. Also, it presents the respective economic value of the water for the reservoirs at different stored water volume conditions.

A importância da gestão baseada na criação de valor para o acionista (Value-Based Management): o caso do Grupo Galp Energia

A avaliação de empresas sempre constituiu um tema de elevada reflexão, sendo que vários especialistas tentam encontrar os modelos que melhor se adaptam a situações específicas e para as quais precisam de determinar um valor. No contexto empresarial português começa a ganhar significância a prática da gestão orientada para a criação de valor (Value-Based Management). O conceito de Value-Based Management assistiu a um particular desenvolvimento nos últimos 20 anos como resultado da globalização e desregulamentação dos mercados financeiros, dos avanços nas tecnologias de informação e do aumento da importância dos investidores institucionais. Vários analistas apresentaram evidência de que as empresas que adotam sistemas VBM melhoram o seu desempenho económico em relação a outras de dimensão semelhante no mesmo setor. É neste contexto que o EVA (Economic Value Added) se apresenta como uma métrica de desempenho privilegiada nos processos de controlo das decisões estratégicas tomadas. No presente trabalho pretendemos abordar o conceito da gestão baseada na criação de valor e a sua importância para o acionista, o que implica rever outros modelos de avaliação tradicionais baseados no valor contabilístico. Como métrica de avaliação do desempenho passado da empresa ao nível da criação de valor vamos dar particular importância ao estudo do EVA, fazendo referência à possível correlação entre esta métrica e o MVA (Market Value Added). O objetivo principal é analisar empiricamente a relação do EVA como medida de desempenho associada à criação de valor para os acionistas com a performance da empresa. Com efeito, vamos efetuar um estudo de caso, que vai incidir sobre um grupo empresarial português, referência no seu setor de atividade, o Grupo Galp Energia, cotado na Euronext Lisbon. Pensamos que a crescente prática da gestão baseada na criação de valor nas empresas cotadas em Portugal e a necessidade de aferir os resultados desta, tornam esta investigação pertinente, para além do facto de serem poucos os estudos empíricos à questão da criação de valor e a sua correlação com o valor acrescentado de mercado e com o valor de mercado dos capitais próprios das empresas cotadas em Portugal.

Microstructure Order Flow: Statistical and Economic Evaluation of Nonlinear Forecasts

In this paper we propose a novel empirical extension of the standard market microstructure order flow model. The main idea is that heterogeneity of beliefs in the foreign exchange market can cause model instability and such instability has not been fully accounted for in the existing empirical literature. We investigate this issue using two di¤erent data sets and focusing on out- of-sample forecasts. Forecasting power is measured using standard statistical tests and, additionally, using an alternative approach based on measuring the economic value of forecasts after building a portfolio of assets. We nd there is a substantial economic value on conditioning on the proposed models.

A prior project, HR-388, (which was entitled "Total Cost of Transportation analysis of road and highway issues"), explored the use of a total economic cost basis for evaluation of road based transportation issues. It was conducted as a proof-of-concept effort between 1996 and 2002, with the final report presented in May 2002. TR-477 rebuilt the analytical model using current data, then performed general, system level, county level, and road segment level analyses. The results are presented herein and will be distributed to all county engineers for information and local use.

Investments and value creation Case pulp and paper industry

Tämä tutkimus analysoi 49 sellu- ja paperiteollisuusyrityksen investointistrategioiden ja yrityksen arvon välistä yhteyttä vuosien 1996 ja 2005 välillä. Teoriaosa luo katsauksen arvonmääritysmenetelmiin ja investointien vaikutuksesta yrityksen arvoon ja arvonluontiin. Empiirinen osa on sekä kuvaileva, että selittävä. Yrityksen arvon kehittyminen mitataan vuosittain lisäarvomallilla (EVA®). Toteutetussa analyysissa yritykset on ryhmiteltyjoko liiketoimintaorientaation tai maantieteellisen alueen mukaan. Yritysten investointistrategiat jaoteltiin kasvumallin mukaisesti T&K:hon käyttöomaisuusinvestointeihin ja yritysostoihin. Kasvumallin tulokset ovat raportoitu yritystasolla. Tulokset osoittavat, että harvat sellu- ja paperiteollisuusyritykset ovetpystyneet arvonluontiin. Arvonluonti riippuu merkittävästi talouden suhdanteista. Yritysten investointistrategiat ovat olleet hyvin identtisiä tarkastelujaksonaikana ja alan suurimpien yritysten investointistrategiat kuvaavat hyvin koko toimialan kehitystä. Pienempien yritysten investointistrategiat eroavat valtavirran toimista. Jatkoanalyysi osoitti, että investoinnit käyttöomaisuuteen parantavat kannattavuutta, mitattuna EBITDA-%:lla ja yritysostot heikentävät sitä. Mitattaessa arvonluontia EVA®:lla käyttöomaisuusinvestoinneilla on positiivinen vaikutus arvonluontiin, kun taas yritysostot tuhoavat arvoa. Havainnot tukevat aikaisempia empiirisiä tutkimustuloksia.

Patenttien vaikutus suomalaisten pörssiyritysten markkina-arvoon - reaalioptiosovellutus

Tutkielman tavoitteena oli tutkia onko patenteilla positiivinen vaikutus yrityksen markkina-arvoon. Aihetta tutkittiin reaalioptionäkökulmasta: miten patentit voidaan nähdä reaalioptioiden ilmentymänä ja millainen vaikutus niillä on yrityksen suoriutumiseen. Lisäksi tutkittiin onko patenttien vaikutuksessa toimialakohtaisia eroja. Tavoitteena oli myös selvittää onko patenttien vaikutus erilainen talouden eri suhdanteissa. Empiriana tutkimuksessa olivat suomalaiset pörssiyritykset ja niiden Suomeen myönnetyt patentit. Tutkittavana ajanjaksona oli 2001–2010. Tutkimusongelmista johdettuja hypoteeseja testattiin regressioanalyysien avulla. Selitettävänä muuttujana oli yrityksen Tobin’s q ja selittävänä muuttujana yrityksen voimassa olleiden patenttien ja tasearvon suhdeluku. Kontrollimuuttujina käytettiin vuotta ja toimialaa. Tulokseksi saatiin, että patenteilla on ollut positiivinen vaikutus suomalaisten pörssiyritysten markkina-arvoon 2000-luvulla. Varsinkin teknologian ja perusmateriaalien toimialoilla yhteys oli vahvempi kuin muilla toimialoilla. Saadut tulokset ovat yhdenmukaisia aiempien tutkimusten kanssa. Aineiston erityispiirteet toivat tutkimukseen omat haasteensa, jotka vaikuttivat muun muassa toimialaryhmien muodostamiseen sekä makroekonomisen ympäristön merkityksen tutkimiseen.

Value based pricing and marketing of marine engines

Objective of the thesis is to create a value based pricing model for marine engines and study the feasibility of implementing such model in the sales organization of a specific segment in the case company’s marine division. Different pricing strategies, concept of “value”, and how perceptions of value can be influenced through value based marketing are presented as theoretical background for the value based pricing model. Forbis and Mehta’s Economic Value to Customer (EVC) was selected as framework to create the value based pricing model for marine engines. The EVC model is based on calculating and comparing life-cycle costs of the reference product and competing products, thus showing the quantifiable value of the company’s own product compared to competition. In the applied part of the thesis, the components of the EVC model are identified for a marine diesel engine, the components are explained, and an example calculation created in Excel is presented. When examining the possibilities to implement in practice a value based pricing strategy based on the EVC model, it was found that the lack of precise information on competing products is the single biggest obstacle to use EVC exactly as presented in the literature. It was also found that sometimes necessary communication channels are missing and that there is simply a lack of interest from some clients and product end-users part to spend time on studying the life-cycle costs of the product. Information on the company’s own products is however sufficient and the sales force is capable to communicate to sufficiently high executive levels in the client organizations. Therefore it is suggested to focus on quantifying and communicating the company’s own value proposition. The dynamic nature of the business environment (variance in applications in which engines are installed, different clients, competition, end-clients etc.) means also that each project should be created its own EVC calculation. This is demanding in terms of resources needed, thus it is suggested to concentrate on selected projects and buyers, and to clients where the necessary communication channels to right levels in the customer organization are available. Finally, it should be highlighted that as literature suggests, implementing a value based pricing strategy is not possible unless the whole business approach is value based.

Performance Degradation Modelling and Techno-Economic Analysis of Lithium-Ion Battery Energy Storage Systems

Transmission system operators and distribution system operators are experiencing new challenges in terms of reliability, power quality, and cost efficiency. Although the potential of energy storages to face those challenges is recognized, the economic implications are still obscure, which introduce the risk into the business models. This thesis aims to investigate the technical and economic value indicators of lithium-ion battery energy storage systems (BESS) in grid-scale applications. In order to do that, a comprehensive performance lithium-ion BESS model with degradation effects estimation is developed. The model development process implies literature review on lifetime modelling, use, and modification of previous study progress, building the additional system parts and integrating it into a complete tool. The constructed model is capable of describing the dynamic behavior of the BESS voltage, state of charge, temperature and capacity loss. Five control strategies for BESS unit providing primary frequency regulation are implemented, in addition to the model. The questions related to BESS dimensioning and the end of life (EoL) criterion are addressed. Simulations are performed with one-month real frequency data acquired from Fingrid. The lifetime and cost-benefit analysis of the simulation results allow to compare and determine the preferable control strategy. Finally, the study performs the sensitivity analysis of economic profitability with variable size, EoL and system price. The research reports that BESS can be profitable in certain cases and presents the recommendations.
