Jara Díaz, Sergio (Elsevier, 1998)From a microeconomic viewpoint, the so-called modal utility in discrete choice models is a conditional indirect utility function, which represents the maximum level of satisfaction that can be reached at given prices and ...

Astroza, Sebastián; Rawoof Pinjari, Abdul; Bhat, Chandra R.; Jara Díaz, Sergio (National Academy of Sciences, 2017)A microeconomic theory-based multiple discrete-continuous choke model was developed to accommodate (a) both time allocation and goods consumption as decision variables in the utility function, (b) both time and money budget ...
-
Jara Díaz, Sergio; Candia, Diego (Elsevier, 2020)We depart from the individual view behind those time allocation models aimed at the calculation of the value of leisure (VoL) when dealing with two-worker households, as this (prevailing) view requires approximations and ...
-
Fielbaum, Andrés; Jara Díaz, Sergio; Gschwender Krause, Antonio (Springer, 2017)Urban transport systems analysis requires some explicit or implicit representation of the network, activity pattern and flows pattern of the city. When dealing with transit design in real systems, detailed descriptions of ...

Schmid, Basil; Jokubauskaite, Simona; Aschauer, Florian; Peer, Stefanie; Hössinger, Reinhard; Gerike, Regine; Jara Díaz, Sergio; Axhausen, Kay W. (Elsevier Ltd, 2019)Being of great importance for transportation policy appraisals, we investigate mode and user-type effects in the value of travel time savings (VTTS) using a pooled RP/SP Mixed Logit modeling approach for mode, route and ...
-
Rosales Salas, Jorge; Jara Díaz, Sergio (Elsevier, 2017-06)Time use models have advanced significantly during the last decade: their theoretical approach has been refined, functional forms have improved and new constraints have been incorporated, among other aspects. However, there ...

Fielbaum, Andrés; Jara Díaz, Sergio; Gschwender Krause, Antonio (Elsevier, 2020)In this paper we study how the spatial arrangement of transit lines (lines structure) influences scale economies in public transport. First we show that the degree of scale economies (DSE) increases discretely whenever ...
-
Basso Sotz, Leonardo; Jara Díaz, Sergio; Muñoz Figueroa, José (University of Bath, 2017)A three-stage game is used to model interactions between users, a shipping company, and a container port. Emphasis is placed on modelling the many services provided and priced by a port in order to compare pricing structures ...
-
Basso Sotz, Leonardo; Jara Díaz, Sergio; Waters II, William G. (Edward Elgar, 2011)There are various components of the total costs of transport: (1) the costs of infrastructure; (2) costs incurred by transport operators; (3) costs borne directly by users (e.g., time and inconvenience costs); and (4) costs ...
-
Gschwender Krause, Antonio; Jara Díaz, Sergio (2007-10)Aunque la congestión y los problemas medioambientales hacen del aumento de usuarios de transporte público uno de los objetivos declarados más comunes en políticas de transporte urbano, las medidas para lograrlo suelen ser ...
-
Gschwender Krause, Antonio; Jara Díaz, Sergio; Bravo Labra, Claudia (Pergamon-Elsevier, 2016)A feeder-trunk scheme has been labeled as superior in urban areas due to the presence of economies of density (decreasing average operating cost) along the avenues served by trunk lines. We compare this structure against ...
-
Jara Díaz, Sergio; Astroza, Sebastián; Bhat, Chandra R.; Castro, Marisol (Elsevier, 2016)We present a microeconomic model for time use and consumption for workers with an improved treatment of the (technical) relations between goods and time. In addition to the traditional time and income constraints, an ...

Jara Díaz, Sergio; Gschwender Krause, Antonio (Emerald, 2005)
-
Jara Díaz, Sergio; Kockelman, Kara (Elsevier, 2001)Microeconomic framework has become a very rich and useful approach to understanding and modelling of travel behavior. This paper covers the topic in the following manner: 1) the basic notion of microscopic perspective is ...
-
Jara Díaz, Sergio; Martínez Budría, Eduardo; Díaz Hernández, Juan José (Elsevier, 2006)By describing the technical process, in this article we argue that cargothat arrives in many different forms are distinct outputs of a port, whose services require inputs that can be grossly defined as labor, space, ...
-
Jara Díaz, Sergio; Cruz Padilla, Diego; Casanova Morales, César (Elsevier, 2016)Travelcards are used in many parts of the developed world as a form of payment for public transport that is convenient for frequent users. In essence it involves a one-time payment T at the beginning of a period that covers ...
-
Tovar, Beatriz; Trujillo, Lourdes; Jara Díaz, Sergio (Springer-Verlag, 2004)In most countries in the world, practically all imports and exports are done by sea. Maritime transport requires port facilities to facilitate the interchange with land transport or interior navigation. Thus, efficient ...

Ramos Real, Francisco Javier; Martínez Budría, Eduardo; Jara Díaz, Sergio (2002)
-
Jara Díaz, Sergio (Elsevier, 2002)This book chapter presents the properties of the conditional indirect utility function corresponding to an expanded version of the goods/leisure trade-off model, which includes work and travel time as direct sources of ...
