On this week’s Insights podcast, Don and David speak with Dr. Trevor Tombe, Professor in the University of Calgary’s Department of Economics and Director of Fiscal and Economic Policy at the School of Public Policy.  Dr. Tombe has published a number of papers related to interprovincial trade barriers including a recent one for the Public Policy Forum specifically covering the benefits to Atlantic Canada from making it easier to trade across provincial borders.  We discuss a variety of barriers to provincial trade including rules and regulations, and we go deeper with a lively discussion of issues such as government subsidies to industry, provincial tax rate differentials, infrastructure investments and other government-related benefits that may provide advantages to industries in one province but not another.   This one got a little wonky but we are sure you will enjoy the conversation.
