Alain Bertaud, a renowned urbanist and city doctor, recently made an appearance on the EconTalk podcast with host Russ Roberts. In this engaging conversation, Bertaud shared his insights on cities and urban planning, drawing from his extensive experience working in various cities around the world.
Bertaud explained that he prefers the term “urbanist” over “urban planner” because he sees himself as a problem-solver rather than a city designer. He likened his role to that of a doctor diagnosing and treating a patient, addressing specific issues such as housing affordability, traffic congestion, and labor market dynamics in cities.
When discussing a specific example of a city facing challenges, such as Tel Aviv in Israel, Bertaud highlighted the importance of considering cultural, geographical, and topographical factors in finding solutions. He noted that in a densely populated city like Tel Aviv, where land constraints limit horizontal expansion, building upwards and investing in public transportation infrastructure, such as subways, becomes crucial to accommodate growth and alleviate traffic congestion.
Bertaud emphasized the need for efficient connectivity within cities to foster economic activity and facilitate the interaction between diverse skill sets and industries. He debunked the notion of self-sufficient neighborhoods and stressed the importance of a well-connected urban fabric to create a vibrant and dynamic urban environment.
Overall, Bertaud’s insights shed light on the complex and multifaceted nature of urban challenges and the importance of adopting a holistic and pragmatic approach to urban planning. By viewing cities as dynamic and evolving entities, urbanists like Bertaud play a vital role in shaping sustainable and inclusive urban environments for the future. Improving transportation in a city is crucial to its overall functionality and efficiency. In a recent discussion between Russ Roberts and Alain Bertaud, the importance of having a well-connected transportation system in a city like Tel Aviv was emphasized. Bertaud highlighted the need for multiple modes of transportation to truly connect the entire city and metropolitan area.
One key aspect of improving transportation in a city is addressing parking policies. Donald Shoup, an expert on parking policies, pointed out the impact of on-street parking as a free subsidy to car owners. Cities like Tokyo have implemented strict regulations on parking, prohibiting on-street parking and enforcing off-street parking requirements. This has led to more pedestrian-friendly streets and reduced car ownership.
Bertaud agreed with Shoup’s assessment and suggested that cities like Tel Aviv should limit street space for long-term parking. Instead, parking should be treated as a separate entity, similar to hotels, with prices varying based on demand. By adjusting parking prices according to peak times and seasons, cities can better manage parking supply and demand.
The issue of free parking in cities like New York was also raised, with Bertaud pointing out that it consumes valuable real estate without any cost to the car owner. This leads to an under-supply of parking spaces and contributes to congestion in urban areas. Bertaud emphasized the need for cities to monitor median commuting times and address any issues that arise, as long commutes can impact the overall efficiency of a city.
In conclusion, improving transportation in cities like Tel Aviv requires a comprehensive approach that includes addressing parking policies, implementing multiple modes of transportation, and monitoring commuting times. By reevaluating how parking is managed and priced, cities can create a more efficient and livable environment for residents and visitors alike. The issue of commuting is one that affects millions of people around the world on a daily basis. Spending hours stuck in traffic or cramped on public transportation can be a draining experience that takes a toll on personal well-being and productivity. In a recent conversation between economists Russ Roberts and Alain Bertaud, the topic of congestion pricing and its potential impact on traffic problems was discussed.
Congestion pricing is a policy that involves charging people to bring their cars into the central city or banning cars entirely in certain parts of the city. While some argue that this is an effective way to reduce traffic congestion, Bertaud believes that the key is to optimize demand and supply rather than simply banning cars. He points to Singapore as a city that has successfully implemented congestion pricing for years, using market principles to manage traffic flow.
Bertaud compares congestion pricing to pricing for a movie theater, where the cost of a ticket varies depending on the time and day of the showing. By adjusting prices based on demand, cities can incentivize drivers to choose alternative modes of transportation or travel during off-peak hours. However, he cautions against outright bans on cars, noting that vehicular traffic is essential for the functioning of a city.
In terms of his favorite city to spend time in, Bertaud praises Singapore for its well-regulated policies and efficient transportation system. However, he also acknowledges the appeal of cities like Paris and New York for their cultural attractions and accessibility. Despite these positive aspects, Bertaud highlights the challenges faced by cities like Paris, where a significant portion of the population commutes outside the city center due to restrictions on building expansion.
As urban populations continue to grow and fertility rates decline, cities are faced with new challenges in managing transportation and land use. Bertaud points to the case of Thailand, where a drastic drop in fertility rates has implications for the country’s future population growth. With no perfect city yet found to balance these complex issues, urban planners and policymakers must continue to innovate and adapt to changing demographics and economic realities.
In conclusion, the issue of commuting and traffic congestion is a multifaceted problem that requires careful consideration and innovative solutions. By implementing policies like congestion pricing and investing in alternative modes of transportation, cities can work towards creating more efficient and sustainable urban environments for all residents. The issue of urban growth and migration to major cities is a pressing concern in many countries around the world. In Thailand, for example, the government is grappling with the challenge of preventing the mass exodus of young people from secondary cities to Bangkok. The lack of economic opportunities and attractive amenities in secondary cities often drive young people to seek better prospects in the bustling capital city.
When considering the demographic trends in secondary cities, it becomes clear that there are not enough people to support significant growth. The limited job opportunities and lack of infrastructure make secondary cities less appealing to young people who are eager to pursue their careers and dreams. As a result, many graduates choose to relocate to Bangkok in search of better job prospects and a higher quality of life.
For businesses, the issue of an aging labor force in secondary cities poses a serious challenge. With a shrinking pool of young talent, firms may struggle to find skilled workers to drive their growth and innovation. This trend is evident in countries like Germany, where the median age of the labor force is steadily increasing, raising concerns about the future sustainability of the economy.
The situation in Japan serves as a cautionary tale, where smaller cities are experiencing a decline in population as young people flock to larger urban centers. The phenomenon of urbanization has left many smaller cities struggling to attract and retain residents, leading to a decline in economic activity and social vitality.
In addressing this complex issue, policymakers and urban planners must consider a range of factors, including zoning regulations and urban development policies. The case of Paris, with its strict height restrictions and preservation efforts, highlights the trade-off between maintaining the city’s historic charm and accommodating the needs of a growing population. While zoning regulations can play a role in shaping urban growth, they must be carefully balanced to promote both preservation and affordability.
Ultimately, finding a sustainable solution to the challenge of urban migration requires a comprehensive approach that takes into account the needs and aspirations of local communities. By fostering economic opportunities, investing in infrastructure, and creating attractive living environments, secondary cities can become more competitive and appealing to young people and businesses alike. Only through thoughtful planning and strategic investments can secondary cities thrive and grow in the face of urbanization pressures. The debate over city density and urban development is a complex and ongoing issue that cities around the world grapple with. In a recent conversation between urban planner Alain Bertaud and economist Russ Roberts, the topic of city density and its impact on urban life was discussed in depth.
Bertaud highlighted the importance of density in creating vibrant and walkable cities, citing examples from European cities like Paris and London, where amenities like cafes and restaurants are abundant and easily accessible. He noted that American cities often struggle to achieve the same level of density due to zoning regulations that restrict building heights and floor ratios, leading to an overemphasis on single-family housing.
Roberts questioned why American cities have adopted such restrictive zoning policies, despite the environmental and social benefits of higher density. Bertaud suggested that the American preference for large homes and yards stems from a cultural belief in the value of space and individualism, which clashes with the idea of dense urban living.
Bertaud also pointed out the resistance to densification in his own town, where residents oppose the construction of townhouses due to concerns about social balance and property values. He noted that this resistance is not necessarily rooted in racism, but rather in a fear of change and a desire to maintain a certain status quo.
Overall, the conversation shed light on the complex interplay between cultural values, zoning regulations, and urban development, highlighting the need for cities to adapt and evolve in response to changing demographics and economic realities. As cities continue to grow and evolve, finding a balance between density and livability will be crucial in creating sustainable and vibrant urban environments for all residents. Paris is known for its charm, beauty, and rich cultural heritage. It is also home to a diverse population, including many wealthy individuals who choose to live in small apartments. These individuals make a trade-off by living in compact spaces, but they gain access to a wealth of amenities, such as restaurants, cafes, theaters, and more.
In Paris, it is not uncommon to find people living in apartments that are only 60 square meters in size. Despite the limited space, these individuals enjoy the convenience of being able to walk to a variety of restaurants and cafes. They can easily meet up with friends, enjoy cultural events, and experience the vibrant city life that Paris has to offer.
This trade-off is based on culture and lifestyle preferences. In Paris, the focus is on quality of life and access to amenities rather than the size of living spaces. The city’s rich history and vibrant atmosphere make it an attractive place to live for those who value cultural experiences and social interactions.
Economist Alain Bertaud points out that culture plays a significant role in shaping people’s preferences and choices. Americans, for example, have different lifestyle preferences compared to Europeans. Americans tend to prioritize space and privacy, which is reflected in their preference for suburban living and car ownership.
However, there is a growing interest among Americans in urban living and walkable neighborhoods. Many urbanists and minimalists advocate for a more European-style approach to city planning, with a focus on creating vibrant, pedestrian-friendly communities. This shift in mindset reflects a desire for greater social interaction, cultural experiences, and access to amenities within walking distance.
Bertaud highlights the importance of random encounters and social interactions in cities. He emphasizes the value of meeting people from different backgrounds and disciplines, which can lead to new ideas and perspectives. In a city like Paris, where cafes and public spaces serve as hubs for social interaction, these chance encounters play a crucial role in fostering creativity and innovation.
Overall, the choice to live in a small apartment in Paris is not just about space constraints, but also about embracing a rich cultural experience. By prioritizing access to amenities, social interactions, and cultural events, residents of Paris are able to enjoy a quality of life that goes beyond the size of their living space. As cities continue to evolve and adapt to changing preferences, the importance of cultural influences and lifestyle choices will remain a key factor in shaping urban communities. When stepping into a new environment, it’s always a mystery as to what to expect. You never know who you will meet or what kind of ideas they may bring to the table. Sometimes, you may even encounter obnoxious people. However, Alain Bertaud believes that obnoxious people are necessary to stimulate new thoughts and ideas.
In a conversation with Russ Roberts, Bertaud discusses the importance of encountering people who are different from us. He explains that cities have always been hubs of innovation and new ideas because of the diversity of people and their perspectives. Even if some individuals may not always be pleasant, their presence is essential in sparking creativity and pushing boundaries.
Roberts shares an anecdote from one of his books about a fisherman who finds himself in what he initially believes to be heaven, only to realize that he is actually in Hell. The story serves as a reminder that rough edges and challenging encounters can lead to unexpected outcomes and growth.
Bertaud highlights the significance of living in a small apartment in a vibrant city. He emphasizes the importance of having access to amenities like theaters, jazz clubs, coffee shops, and restaurants, as well as the value of random encounters with strangers on the streets. These experiences contribute to the richness of urban life and foster a sense of community.
However, Bertaud also points out the restrictions placed on minimum apartment sizes in some cities. These regulations, intended to protect residents from cramped living conditions, often limit affordable housing options and result in underutilized buildings. By allowing for greater density and flexibility in housing options, cities can create more inclusive and dynamic neighborhoods.
In conclusion, Bertaud calls for a reevaluation of zoning regulations to eliminate unnecessary restrictions and promote more efficient land use. By understanding the trade-offs between building materials, land costs, and infrastructure needs, cities can create environments that are both livable and sustainable. Embracing diversity and welcoming challenging encounters can lead to a more vibrant and innovative urban landscape.
